Recommended Posts

Hi everyone,

Greetings from Indonesia 😁

I need a solution here about my bluebolt,

I bought 10 bluebolt to start new colony in a tank 30*40*40 it had been cycle 2 months and the parameter nitrit 0 nitrate 10 pH 5,5 tds 100 GH 4 KH 0, 

At first month the bb started faded the colour, and one by one they death and left 5 of them, and then I bought again 15 more, and the killing's continue until now I only had 12.. I water changed every 1 one week 20%. I always took water test and the parameter is always fine, nitrite below 10 and pH constantly in 5,5. Ammonia is 0. Can anyone help me what am I do wrong.. so sad to be honest losing the beautiful creature..

Sorry for my bad English, keep safe everyone

We should probably start with the basics. What water are you using as only RO water with remineraliser is probably going to work, even if your water source has the right parameters. I have experienced this in the past with tap water and had similar happen as you are experiencing!

The other problem you may be having is your temperature there is too high, do you know what the waater temperature in the tank is. I looked at the internet and your about 33 degrees in general, taiwan bee shrimp would struggle above 27 degrees and probably start dying around 30 degrees (water temperature). As a temporary fix you could get a couple of bottles of water, freeze them laying flat, then put 1 in the tank, when it has thawed out swap with the one in the freezer. Of coarse you will need to think of something more longer term?

You could also reduce your weekly water change to 10% and make sure you add new water very gradually,  some sort of dripper is best. I doubt this is your problem but just an additional note.

Agree with Simon here.

What is your water temp?

Hi jayc and Simon, my water temperature is 23 c and I'm using RO water and mineral to match the tds and GH, for my remineraliser the tds 100 is equal to GH 4.. that's why I set the tds 100.. but still... They died too.. any idea to help me?

That temperature is good so as ong as water stays at that and doesn't go up at any point in the day that is fine. Using RO + minerals should also be perfect!

When you get shrimp you should always drip acclimate them, otherwise you get deaths for up to a few weeks later.

What sort of setup do you have and what is in the tank, substrate, plants, filter, other etc?

When the shrimp die do they have anything to them that may help, apart from losing colour that you already mentioned?

Where did you get the shrimps from, was it a reliable source such as a breeder?

Thx for replying Simon,

I have UGf (filter pad at bottom, and second layer substrate bactersand lowkeys) and qanvee double sponge with Bacter media "neo soft" (the media can buffer the Water too)

Plant just  duckweed,marimo moss ball and shrimp shelter.

I always drip acclamation my shrimp with 1 drop per second, and it take hours before I put in the tank...

They died like usual, just standing on their feet, I think they swarming the soil to find food.. but the fact the shrimp is almost dying... They loose the colour 3-4 days before dying...

I get the shrimp from a reliable breeder, but their tds is 120 GH 4 (he is using lowkeys mineral GH+ tds 120= GH 4)

I don't use the low-key, I used local remineraliser tds 100= GH 4 (using tetra test kit for GH)

 

Really confusing, is the pH is too low?

I don't think the PH is too low, unless the test starts at 5.5 then it may be anything below 5.5? Mine was PH5 - PH5.5!

Is the remineraliser meant for shrimps specifically or just general?

Do you feed the shrimps, as there isn't much surface area (leaves etc) for biofilm to grow? Maybe get some indian almond leaves and Bacter AE if that is readily available to you? If they are swarming to find food, maybe there isn't sufficient food to support the colony?

They behaved strangely, if I turned on the lamp, they will hide in the almond leaves, yes I feed the every 2 days, I feed the Bacter are, snow flake and others... 

The remineraliser is for shrimp only

About the pH, I test it with tetra test kit, and it only began with pH 5, and the pH is sometimes 5 (1 day after WC) and 5,5 if I just water change the tank... I already turned the aerator widely, so I don't think they lack of O2... So really don't understand what happen

That all sounds good and you seem to have everything you need and I can't see anything obviously wrong from what you have said!

You may have to just give it a bit more time for the tank to settle down.Unfortunately it is similar to my last attempt where I ended up giving up with shrimps in that tank and put fish in the tank instead! With mine I assume it was the substrate but I don't realy know, but the parameters have always been ideal but the plants aren't doing as well as they did with a different substrate? When my fish die off I will try again with the same substrate that worked well before!

You can try looking in the disease thread of this website just to see if anything there may look like an issue!

I can't see anything wrong either.

You can try increasing TDS to 120, and pH to 6.0. Just to give yourself a small buffer in case test kit measurements are a bit inaccurate.

Hi jayc,

Hm, I'd like to know what is the parameter for bluebolt? I'm afraid if I raise the tds the GH will be messy..

How I buffer the pH?

 

 

Regards,

GH 4 to 6

KH 0-1

pH 6 - 6.5

TDS 120 - 150

Temperature 68°F to 72°F (20°C to 22°C).

Raising TDS from 100 to 120 as I suggested is only a very small amount. At most, your GH will only go up by 1.

Do you mean ... how do you increase pH?

Raise KH is the answer.

If your pH is at 5.0 now, you will only need a bit of carbonates to raise it up to 6.0.

What is the KH of your tap water in Indonesia?

You can use dechlorinated tap water. Mix a bit with your RO water during water changes.

Generally accepted parameters range for Taiwan bee are GH 4 - 6, TDS 100 - 160, so you maybe should try getting nearer the middle of those figures as you are at the lower end, do it slowly though by adding just a small amount of remineraliser each day!

Simon

Edit, looks like JayC and I cross posted at same time. I would be reluctant to mess wth the PH as you probably have ammonium in the tank at the moment with your PH, whereas that converts to ammonia when PH is increased and that would cause a whole new problem with cycling. Ammonium is harmless to shrimps, where as ammonia is toxic so increasing the PH should be done by cycling the tank without the shrimps in it. A lot of people who have been very succcessful in shrimp keeping have PH below 6, my tank ran at 5.5 but started about 5 so similar to yours and was very successful.

Hi Simon and jayc

After I read the shrimp disease topic I think my shrimps are having bacterial infection.. loss of colour, and the antenae, and when the shrimp dead their head have brown colour... 

The bb is still dying every week, than my friend ask me to water change for 40%  and put seachem stability routine.. it have been almost a week now, and 0 death.. oh btw the bb is 5 left in the tank. They seem happy now and actively, but I don't know maybe I'm wrong..

Really sad having a lot of death in the tank...

If the deaths have stopped, then that is good news.

Keep a close eye on them and look for brown spots, like the shell is rusting.

All you should do know is make sure the tank parameters are stable and give them a clean, cycled tank.

Hi Simon,

the one that had the rusty shell already dead... Hope everything gonna be okay, really desperate having high death rate in the tank.. may I know what causing the bacterial infection? The antennae is short.. is bb  antennae is short or long?

Hopefully you are over the problem and all goes well from here onwards, as JayC says, just keep a close eye on them for a while. I did have rust on a few in my mixed tank, always red ruby bizarrely, none of the others and they were all shrimps I had for about a year so can't blame the person I bought them from! It went on for a while with me just culling the odd shrimp every few weeks (1) and didn't seem to spread, so hopefully that will be what happens with yours and the remaining will be fine.

All the taiwan bee have long antenae normally so as above just keep an eye on them, the antenae may grow back with time.

I think it is usually down to poor water quality and/or nitrates which weaken the shrimps immune system and then the bacteria attack! That may explain why the large water change you did helped/stopped it? Or it may have not been properly cycled and hopefully it now is? A lot of times the bacteria are always in the tank but harmless to healthy unstressed shrimp! I see from your first post you were doing 20% water change each week and so that should be ok, as long as you add the new water very slowly (a dripper is best) and the parameters of the old and new water aren't too different. You could reduce that to 10% each week as shrimp aren't very messy and that should reduce any fluctuations?

I hope it all continues to do well, keep an eye on the shrimp for now and let us know if you are still having problesms, hopefully you have a mix of male and female, and they will help replace the dead shrimps and increase your colony!

      Great idea! Please document your journey here. I have no experience with marine shrimps, so cannot help you. But what you have listed above seems like a sound plan to get started.   
    • sdlTBfanUK
      That sounds like a fun project and look forward to hearing how it goes!  Hopefully someone will have some useful advice/tips etc?

      I have an idea. And considering I’m terrible at being concise, I’m sure it’s gonna take me a while to explain it.   Essentially, I want to do a nano marine rockpool tank, with just crustaceans and molluscs (and perhaps a seastar or two). And I really don’t know how plausible it is, but I’m pretty intent on finding out. I don’t know if anyone here has any experience with marine shrimp, but I figured I may as well see if any of the Aussies here are familiar with the shrimp I want to keep. So this species of shrimp is actually the species that got me into the hobby! I found them on a camping trip, and they were just so active and engaging, and I just fell in love. Then I went home, did a bunch of research, and got an aquarium. They’re part of the reason why I’m so interested in shrimp. Now I’m on holidays again (in a different place in Vic) and they’re everywhere in the tide pools. Millions. The species is ‘palaemon serenus’, the red-handed shrimp, and they grow to about 6cm for big females (which I discovered last night) and I think 3-4 for males. Just from observation. They live primarily in colonies of 10-30 under rocks during the day, venturing out when they feel safe, and going everywhere once it gets dark. They’re omnivorous, eating pretty much everything they can get their little claws on (including my fingers and toes). They look rather like freshwater macrobrachium, to be honest. I’ve had a look and it’s legal to collect from this location. There aren’t limits on anything I want to collect. So, I’m thinking I’d do a 20 litre tank for the meantime (until I can get some awesome 30ish litre low-boy tank). I’ve got one at home that could be set up as soon as I’m back. If I take home a big rock and sand, then I should have beneficial bacteria sorted, as well as a food source. The rock would have plants and a bit of algae and all the other good stuff you find on the rocks they like. Other than using salt for water changes, I’d run the tank like a freshwater tank - sponge filter for filtration, freshwater light, no heater, fortnightly or monthly water changes. I’d love to add a couple little fish if I can catch them, but I have no idea how to identify whether they’ll grow or not. Same deal with the majority of crabs (although I have ID’d a few species that would work). And unfortunately no nudibranch either… although I found the CUTEST little one last night. They’re apparently super specialist in terms of diet, and I don’t have the time to observe one for hours to see what it eats, ID it, work out how to cultivate it, and all that. So, that’s the plan. I would love any advice, recommendations, or criticisms you have. I understand there’s a good chance this could be too ambitious, and the well-being of the animals is number 1 priority, so if it sounds like it’s a bad idea then I’ll just scrap it. But I’m pretty keen on finding out a way to make this work.

      I have had fungus each time I set up a new tank, but it has always just disappered on its own after a month or two, and has been varied in appearance each time!
    • Dirk De Bakker
      Had a go searching / feeling throught the substrate for the tabs but no luck.  They might have dissolved or become soggy so I can't  feel them.  I have a bucket sample of substrate brewing at the moment for a 24 hour test and its already steadily rising the TDS.   Looks like a just wait and see...... Thanks for all the help as ususal it is appreciated.  Dirk
