New tank and shrimp

I reckon you could get away with 10 neons, maybe a few more

I have a mix of 10 fish, 6 ember tetra and 4 neons in my 30L. The embers are a bit smaller but you have a larger tank so as Crabclaw above, 10 seems about right!

Might have made a lil mistake.

Amano and cheery shrimp went into the tank fine yesterday after about 3 hours of acclimitising.

Come down this morning and the tank as just a whirlwind of activity, so decided to try out the new shrimp food I gave them. I should REALLY have read the instructions 1st, I've put in about 4 times the recommended amount of food!
After the initial feeding frenzy (wish I recorded it), everything has gone quiet. Everyone is just chilling down the bottom of the tank.

Tried to remove as much food as I could with my tweezers, but think I'll do my water change tonight when I get back, rather then wait till Tuesday and see if I can hoover up the remaining food.

Edit - On a side note, those amano are giants compared to the cherry shrimp!
Also looks like I had a successful molt, yesterday morning, before the extra shrimp arrived, I noticed what looked to be the left overs off a shrimp and since they were all accounted for, I'm assuming there was a molt in the night.

It is usually fairly easy to tell the difference between a molt and a dead shrimp, a molt looks like a ghost and is clear like glass, whereas a dead shrimp usually goes pink and doesn't go clear?

I usually base feeding on half of the manufacturers recommendations. I hope it all works out fine! Perhaps don't feed for a few days? Good idea to vacuum some of the excess food up if you can?

You were wise to not get too many Amanos as they will be the more dominant over the smaller cherrys!

You might have witnessed breeding behaviour. Look out for a berried shrimp.

Further problems unfortunately.

Did a 50% water change on Sunday and turned my CO2 back on today, had it on really low.
Tested my PH and it's dropped down to 5.7, KH is 0, GH is 6.

Not sure what's gone on, I did my normal water change, RO water with Salty Shrimp GH/KH+, I did top it off with a little straight RO, but I would say that it was less the 5% of the water change.

I've turned off my CO2 to see if my PH rises, but why has my PH dropped so low and where has my KH gone?

Is this something to do with my tropica soil?

Wow, that's a huge water change, I wouldn't do more than 10% per week myself now the shrimp are in there, I only do 20% in the tanks with fish as well as shrimp? Shrimps don't produce much bioload so don't need much water to be changed!

The soil will reduce the KH and PH from my experience (your original post was PH5.8 so that is about the same) but as a real guess changing so much water may have caused the problem if some shrimp have died, did you drip in the 50% new water. CO2 is very risky though so unless it is REALLY a must I would leave that off, same for fertilizers? The soil will eventually lose its ability to buffer the PH but that may be a long way off yet, especially using RO water it will take longer as that has a low PH to start with! 

If you did such a large water change to try and get the parameters better then you shouldn't do that once you have the shrimps in the tank as cherry shrimps will adjust well to different parameters, even outside their ideal parameters but by mixing 2 waters with different parameters would be too much for them. Only do about 10% each week and slowly add the water. The shrimps will do better with stable water parameters outside their normal range than quickly changing parameters every time you do a water change!

Cherry shrimp are usually fairly easy and adaptable so hopefully you haven't lost any/many?

Still chugging along, sorted out my PH and finally got some green neons in the tank.

Do love watching the shrimp, espeically the amano, they're so active, well, greedy. I'm sure I saw 1 suplex another other a pellet.

How often do shrimp molt? Saw another 2 big amano molts this morning (all accounted for).

Also, any idea what's up with this cheery shimp? I can't tell if it's some kind of white stripe? Definately not seen it before.

And these have appeared on the side of the tank...

Good to have an update!

Do the white spots on the glass move at all, do you have snails? I can only see blobs, but I get similar that are assassin snail eggs though they are a bit smaller I think?

The white mark is about the place where the moult starts I think so it may be related to that and if so hopefully it will be a successful moult? Young shrimp moult often as they are growing really quickly, but I a not sure how often adults moult?

They don't appear to be moving.
I do have 2 nerrite snails in the tank.

Nerite snails are bigger than assassins so maybe they are snail eggs, that would be great!

Just keep an eye on them and see if they move from where they are for now, unless someone else thinks they are something else?

Hope the neons are doing well and it will make the tank more interesting to watch!

Simon

edit - just read up that the snail larvae need brackish water so I guess that won't work, on the plus side, I guess you can never get over-run that way!

Had a bit of trim of the plants today.
The cheery shrimp, were going crazy over my hand, used to have that problem with cleaner shrimp, didn't think fresh water shrimp were like this.

I can’t tell with the first one, but the second definitely looks berried to me.

They both look berried to me! The eggs start yellow and then change colour as the yolk is used up so they are at an early stage! The eggs of mine go grey as they mature and they are microscopic and clear coloured when newborn so there maybe a period where the eggs have gone and you can't see the shrimplets, until they colour up a bit and start roaming/venturing out and about?

Thats a very nice snail also!

The things on glass could be limpets.

 

Didn't see this thread before (I don't visit the forum too often) but would have suggested not adding any KH to the tank and going for tigers instead. The KH disappeared because the soil absorbs the KH. You have low pH because the soil is releasing tannins, humic acid and/or fulvic acids. By adding KH to the tank, you are causing pH fluctuations and potentially TDS fluctuations as well. This can sometimes cause havoc to the tank inhabitants.

If you wanted to exhaust the substrate (make it so that it no longer lowers the pH of the water), I would have recommended doing this prior to adding any livestock.

 

Sorry if I may have repeated anything, just kind of skimmed through some of the post.

Great to get pictures and an update and assume from the photos it is all going well and hopefully you are getting plenty of shrimplets to watch!

Merry Christmas to you too.

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony. 
    • sdlTBfanUK
      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
