Stocking a 5 Gallon

Recommended Posts

Crabby

Hey folks!

So I got myself a little 5 gallon (20L) recently (it was free!) to use for quarantine. I’m going to use it to qt some cory cats and maybe some tetras or gouramis for my community tank. The thing is, I’ve got it set up really nicely in my room and I want to have it actually stocked. I definitely don’t want a betta, but I found some super cute guppies on gumtree (Wild Thai Orchid) that I can never find locally. How many guppies do u think I could get in the tank?? The seller only has 4 pairs, so is selling in pairs but not trios, so that could have an affect on the amount. I also plan on adding shrimp, either of a neo or caridina variety, or native - like dae or chameleons. 

So my questions are: how many guppies could go in the tank (assuming they breed and I keep the babies in with them for about a month each time), could I fit in anything else (with a pair or 4), like a couple of chilli rasboras or rocket killies, and will the shrimps be enough for a cleanup crew, or should I add an Otto or something?

Cheers!

HAHA LOL.

All my QT tanks have been used for other shrimp or fish as well. I can never keep a QT tank for very long.

 

A 20L tank isn't very big, so 5 or 6 initial guppies accounting for babies in the near future. 

The tank can hold some shrimp but I would think it is too small for another type of fish.

Great. I’ll probably change it up at some stage to feature some other cute nano fish, but I’ll keep it simple for now.

Can we get nerites in Australia?

How about one male two females and some rocket killies? I think that would work and maybe even some shrimp also if it’s not intended for breeding. You can always relocate some of the killies to your community if it doesn’t work.

Sorry not shrimp snails.

No I intend to breed. As I said the guy is only selling in pairs so cannot do a trio. Problem with the killies is that they prefer schools. It’s one or the other really. And I can do killies any time, so I’m going for the guppies for now, unless anyone has a good reason why I could do both.

 

The only snails I’ll do are nerites, so they don’t breed. Waiting for aquagreen to get their native nerites back in stock.

In terms of shrimp, could I do natives like dae or chameleons? ( @jayc)

They only breed in brackish but still lay infertile eggs everywhere and it looks disgusting in small tanks. I’d recommended rabbit snails as they have two genders and will only breed with the other sex so make sure you get all males or females the only downside is they are a little pricey.

Even if you get both males and females they only give birth once a month to two baby snails.

Rabbits are crazy cool. But they’re big and totally pricey.

I’ll probably just avoid snails altogether. Shrimp will do.

Actually I'm starting to think that I could do a pair or two of rocket killies to hang out up top, as the guppies mainly explore the top to middle. I don't think that 6-8 adult nano fish in a 20L is tooo much, is it? With babies it would just be survival of the fittest, I guess, and those who make it go into my big tank or get sold. And I'm still planning on keeping some chameleons or my TTs in here. I might get some DAE eventually, which would QT and grow in this tank then move to my 110. 

Can I have some opinions on this from the mods or anyone who cares?

Cheers!

That probably is a bit too much fora 20L I have 8 fish in 30L (each fish max 1 inch) and some shrimps and snails. Guppies produce quite a ;lot of waste as well! I would personally pick one or other, either the 6-8 guppies or the 4 rocket killies, and some shrimps. As you state, the guppies will have babies so that adds to the bioload etc as well? Would the killie eat the baby guppies? As you have already said, it is probably a case of pick one or other??

If you really want to mix then I MAY try a pair of killies (though you say they are schooling fish) with 2 pairs of guppys (check they are compatible first in a small tank though) at the most (plus shrimps). The other thing to bear in mind is that if it is a 20L tank, it probably only has 16L of actual water with other bits in the  tank (substrate, heater, filter, ornaments, plants etc etc) and it not filled to the rim - my 25L has 20L of water, my 35L has 28L of water? 

As for snails, it does add another interest to the tank, I keep assassins in all my tanks, they do breed (slowly) but even I can easily catch them when their are too many. They will help keep the tanks cleaner (glass etc) and devour anything that may die as soon as it dies, so I always include some snails!

You should also plan to do maintenance and water change once a week of about 20% if sensibly (not over) stocked.

If you decide in the future to get nano fish like the chilli/spotted rasbora then 8 of those would be what I would (and had planned for my 25L if the betta didn't survive) with no other fish of coarse?

Hope this gives you something to mull over, but I would not class myself as an expert..............

I don't see why not. If you are buying from Aquagreen, they might have some DAE or Chameleons too.

You could stretch the total population of the tank if you get a large external canister filter. By large I mean something that is aimed at filtering a tank larger than a 20L tank. That will increase the bio filtration and you could stock more in the tank. Just don't go too crazy.

I have been looking around and the general consensus is not to keep guppies with killis, so you would be better off one or the other type and so I guess you would pick the breeding guppies? I would just start with 4 guppies though as they will produce 2 lots of babies anyway with the 2 pairs!

I’ve kept them together before, and while there were no babies the killies have such tiny mouths that it wouldn’t make a huge difference.

Yeah I think it’s just a thing of finding a nice looking snail that won’t ruin my scape with eggs or overbreeding. I’ll look into it a little more.

Yeah of course

That was my plan. Just was worried that chameleons might be too small?

I wish this was an option, but as I said it’s in my room, in a very small spot/setup. I’m using an eheim 100 air pump with a sponge filter.

one or the other

Yeah okay I think you’re probably right. I’ll just keep it simple. Maybe I could get another ‘QT’ tank in the future 😉

Thanks so much guys! I really appreciate the help!

Hey all, 

so at the moment I’m cycling the tank, and I’m using the ‘shrimp cycle’ method - using a piece of raw prawn or fish to produce the ammonia - and I don’t know when I should take it out... It smells super bad, and it’s in my room. So I don’t want it in the tank any longer than necessary. If I’m already seeing readings of ammonia can I take it out and let the beneficial bacteria handle it from there? Or do I have to wait until I start seeing the first readings of nitrates?

Cheers!

This.

But, did you use a whole prawn?

Now that it is decomposing, you only need a small sliver for it to keep producing ammonia. Chuck the rest away.

Aah yes thanks jayc! I’ve been using a chunk of raw fish. I’ll get rid of most of it ASAP.

Not sure if I should create a new thread for this question, but it’s this - is a 6 watt LED good enough for keeping hairgrasses in a 5 gal? The tank is 26 cm deep - only 22 if u go from substrate up - and I want to keep some eleocharis parvula, and eleocharis caespitosissima. And maybe some Alternanthera Reineckii mini. The light I’m looking at is this: https://www.thetechden.com.au/Pet_Worx_Multi_Spectrum_Mini_6w_Clamp_LED_Light_p/ba02.htm

The wattage isn’t that important what you should be focusing on is lumens and kelvin (warmth) the light says it’s 6500k which is good but doesn’t say how many lumens (brightness) it is. I would find out more about it before making a purchase. Generally a plant will need 20 lumens per litre of water.

 

1 watt= 30-55 lumens

I would have thought this would have been more in relation to depth than litres, as my tank is quite shallow in relation to say a 5 tall, while it still has the same capacity.  Wouldn’t that make a difference? 
 

Another site mentions it has a light frequency of 460 nanometers. Does that affect anything?

That’s the colour of light so 460nm is referring to the wave size

That light sounds like it is about right for the tank, mine has water 22cm deep and I have that TYPE (LED) of lamp 6W, 6500K, 500 lumens. I tried some grass that I bought that was on a metal mesh that had a plastic coating over the mesh. It didn't do very well and went a bit yellow (didn't die though) so I don't know how well it would grow, but would give it a go anyway, there's little to lose? I removed it as the plastic started coming off the mesh and the mesh started to rust - looked horrible? All plants take some time to settle in though so may look a bit uninspiring for a while until the roots establish? In my newest tank ALL the plants looked bad for a while but none actually died and now they are flourishing (too bloody well)!

I found this link which may help you decide? I assume you are using a soil substrate?

https://www.aquascapeaddiction.com/articles/dwarf-hairgrass-carpets-made-easy 

Your actual question though I can't help much with and will hope others will help there. My philosophy is 'try it and it either will, or won't work', but the grass I tried was the only plant that I have ever discarded and that wasn't really anything to do with the plant, more the mesh it was supplied with?

The only other thing I can think off that is related is, lots of people use CO2 with grasses etc, but this is best avoided and not necessary as it will live without it (It would do better with CO2 but the risk to shrimps is too great to warrant it, only use CO2 for a plant only aquascape tank).

Thanks Simon, that's really useful! I don't use a soil or planted tank substrate, but I'm dosing ferts and using root tabs. Mine didn't come in mesh or anything, so not too worried about that. I've bought the plants but not the light. Plants are quarantining and looking fantastic, so I really hope that they will do well in this other tank. I'm not going to use CO2, though.

That link was really helpful. I think I will just go for that light, as it's the nicest I can find nearby without resorting to the deathtrap of low-quality products that is eBay. 

Cheers,

Crabby

I'm not too sure how well grass will do without soil substrate, which is the usual substrate for planted tanks. I would expect the plants to take longer to settle in without soil so don't be too quick to remove plants until you are really sure they are completely dead/dying! They will all get worse before they get better.

Too much fertiliser can also be dangerous to shrimps?

      Um, because I’m all over the place I thought it pertinent to mention I’ve slowly lowered my GH to 5-6 over the last week and a half, or so. Slowly, but these shell issues existed long before adjusting the water parameters. I suppose it’s possible this could have finished off the injured shrimp, however, the parameters are, from what I can gather, a little more superior at this time. The GH was lowered by monitoring my TDS drop closely. I dropped the TDS by around 2 points daily. At this point, I’m sitting at:   PH: 6.2 GH:5-6( during testing, the color teeters between 5-6 drops for a change) KH:0 TDS:140 Temp: 72f   So, now that I’ve completely sworn off of fertilizers, I haven’t seen any increase or decrease in TDS / GH without my own manipulation. Second and third generation of shrimplettes are doing well, and aren’t showing any signs of discoloration. Another mama likely soon to drop as her eggs have easily visible eyes.   
    • Steensj2004
      I apologize for being unclear. I had ordered one before asking more specific questions. So I simply located a different one and order that( the one you green lighted), while also canceling the less desirable one. Also, the one you told me to buy, was considerably cheaper, while retaining the same no additive ingredient list.   No signs that the oregano leaves were touched this AM, but, there were multiple shrimp surrounding them, while several were perched on them. I’m not sure how much they need to ingest to really help, but hopefully the sampled a little bit overnight. Now, my problem is locating a food that they will attack, to place into the tank. Would it be possible to mix some BacterAE/ Shrimp Fit powder into oregano oil water? They seem to feed on that when it’s added to the tank.... otherwise, I’ll use some rephasy, newt made, with oregano oil water added.... or something similar. 
    • Steensj2004
      In relation to the PH, what is too low? Because several people in other groups act shocked at my PH at 6.1-6.2. The substrate is ADA and has always buffered to that range. Even the Fluval Stratum I used in the smaller 5 gallon buffered similarly.
    • sdlTBfanUK
      You are indeed correct in that I didn't see a cycle as such, I only had nitrates of 25 to start (cooked prawn) and that dropped but also as you say the PH was very low, below 6 so a proper cycle may not have happened - well spotted, I had forgotten about that. I set the tank up in June so if it isn't cycled by now though I guess it never will be? Incidentally I have only got the Ph up to 6 (recently) by putting a bit of the old rock back temporarily, and possibly that caused the tank to cycle or something??? I have thus far got 4L of RO water and hope to get more done so I can do a approx 50% water change at the weekend. You make a lot of valid points and thanks for giving me more to go on, maybe the plants aren't as green in this tank because of the different parameters and the substrate isn't as bad as it appears? The other tanks have Ph 7.5 so quite different! I like your point one and that seems to be how most people think in the modern world, but I am 100% sure it is my fault one way or other, I am old school! I am however physically restricted so it isn't anything I can do anything about! Got friends coming on sunday so if I get the water ready they can lug the buckets of water around................. I will get some rubber gloves anyway as that means I can rule that out, and give me peace of mind for the future that I won't accidentally contaminate the water by mistake? I have been using a lot of cleaning products (scrubbing floors) around xmas which makes me think I may have contaminated the tank without realising??? Simon

      Just to update that I went back to my normal, very low dose of fertilizer, but the Ludwigia are still dying, from the bottom up.  The tips are green and growing, but the bottom parts are rotting away.  So far, I can only think of two possible reasons: 1) I have been feeding my shrimp less, so maybe they aren't making enough ammonia and nitrates for the plants 2) About 2 months ago, I changed the lighting so that it was a complete blackout at night and only 7 hours of medium light a day.  This did a great job of getting rid of algae that was growing on the plants, but maybe now I need more light again?
