Hi SKF,

 

I'm liking the Australian native shrimps more and more.

I'd like to get some Caridina sp WA4 North Australia Chameleon Shrimp. Maybe 10 or so.

 

But I know very little about it.

 

Can someone fill me in on ideal water parameters, temps, food, etc?

If you know where I can get some for a reasonable price, let me know too.

I saw them on the list there. The price is ok, and I'll use it as a baseline.

But there is little to no info on the Water Parameter requirements.

 

We need someone to do a write up.

Where's Baccus or North Boy?

I keep mine in a variety of tanks and they seem to be doing well in all. Plenty of berried shrimps and lots of juvies to be seen. All are based on ordinary Sydney tap water (pre treated for chlorine/chloramine), I think it is around 7.5. I don't have RO.

The sand substrate tanks means they look a bit pale, but when placed in tanks with dark substrate they colour up beautifully. 

One tank that has a shrimp substrate  has a lot of leaf litter and when I move it around there tons of Chameleon juvies. They seem to like hiding amongst it. Another tank has lots of scoria and larger rocks, and they are very busy in that tank, always grazing(?) over the rocks.

Most snippets of info say the Chameleons like it a bit warmer 28-30, but  will tolerate cooler.   I had a heap breed up at 25C, but it did take them a long time to get going after I got them from Aquagreen.  ie 3-4 months to settle into the tank.  Getting used to the cooler water temps *might* have been part of that settling in process.  After an unfortunate H2O2 overdose, I had to get a second lot from Aquagreen.  I've had these for ~2 months now and while I see berried females I haven't seen any juveniles at all... I'm rather hoping this second lot is also still in a settling in phase.

 

They are a great tiny shrimp.  They are a lot bolder with NO fish around (you'll see them a lot more).  I have a population persisting in low numbers in a big planted display tank that contains a heap of fish that could eat them.. the shrimp are small and secretive enough, and the tank is complex enough for them to survive... but spotting the Chameleons is a bit of a rare privilege ...in comparison to the DAS that walk around in plain sight giving the fish attitude.

Thanks for that Grubs. 

Valuable info, even for that H2O2 overdose  :phew:

I'll make sure I steer clear of that.  :smile:

 

Any info on TDS parameters?

I'm assuming lower than 100. At least that is what I am going to set my tank up for.

Dave from Aquagreen gave some info on hardness in this thread: http://shrimpkeepersforum.com/forum/index.php/topic/6595-can-you-spot-the-chameleon-shrimp/?p=92413

 

Mine are at ~350µS, 8 dGH, 2 dKH  (~180TDS and  GH ~140ppm and KH ~35 ppm).  If I don't start seeing more juveniles in the tank soon I'm going to try increasing the hardness a little more. I have a theory that the hatchlings are being born but not making it past the first moult.

I keep mine in with my cherries at 24-25*C, pH 7. They tend to hide alot as mentioned. If I were going to keep them on their own, I'd choose water parameters closer to those for cherries than for CRS.

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.
