I have noticed in one tank that all the babies and some adults are lighter in color like yours fishmosy . But in my big tank with the fish , they are darker in color and the babies are showing the stripes already . So i'm starting to think if there is no predators around they stay a lighter color . If there is predators around they go darker to match the substrate.

Its certainly a possibility about the predators. It makes logical sense. 

I dont have fish in with my chameleons, yet mine have made a dramatic change in colour since I boosted the TDS to 200 and maintained it there. Will post pics soon.

One thing I noticed today was that the eyes of my chameleons are red surrounding a black centre, whereas my cherry shrimp have completely black eyes. Could this be a way to tell them apart? Anybody else seen this difference?

My son has a tank with guppies in it and they had some fry so i done a test on sunday. I put two small fry in the chameleon tank to see what happens . Yesterday i noticed the young shrimps are starting to change color (going darker and getting stripes ). So it comes down to having predators in the tank for the good colors

How big were the guppies? I dont think fry (as in < 1 cm) would register as a threat to the shrimp.

they are about 3 cm ,

In my other tank , the chameleons are with black tetras , rasbora and neons . The black tetras swim down near the bottom up and down slowly like a shark . The chameleons are nice color . I dont lose that many in that tank because i make sure the fish are full all the time .

Ah, 3cm is not really a fry. It makes sense that predation avoidance would be a reason for colour change in chameleons, particularly given they are not a large shrimp.

Just updating this thread.

Here is how the tank looks now since my makeover. I've removed all the snails as I needed them in another tank and I dosed the tank to get rid of the hundreds of planaria. I've added a typus and a couple of gracilirostris, and some of the red Vallisneria which I got from Cairns. Breeding has slowed down considerably probably because the tank is unheated, but I still see the occasional berried female.

Same same. Still breeding like anything but no consistency in the colouration of the offspring - except to say they seem to be the lighter browns, blues and reds, rather than the nicer dark brown/black and white. I haven't been selecting offspring to breed from as I've been focusing on other projects.

I caught my son playing in the tank TWICE last week so its in desperate need of a re-scape. I'll probably tear it down shortly and replace it with a larger tank for some Sulawesi shrimp, which would suit the room better (this tank is in the hottest room in the house - although that hasn't really bothered the chameleons). I think that would be a good opportunity to start a highly selective program with the chameleons on my shrimp rack. I'll probably start with chameleons from wild caught stock, specifically the darker brown/black with white stripes (as that is my favorite pattern) and then heavily select the offspring to select for that pattern and colour.

I notice that many of my chameleons tend to be a solid dark brownie red with a light back stripe down the centre of their back. I also get the dark and light striped ones like a zebra but I usually only see around 4 like that. I think the others tend to take on the more solid colour because they usually seem to hide out in the large hollow log that dominates their tank. Even when the chameleons are out and about in the tank they are often still only to be found under the hollow log.

The tank only houses one potential predator Spotted Blue Eyes so that might also have a bearing on the shrimps colouration, but the little Blackmore River shrimp don't seem bothered by the Spotted Blue Eyes and can always be seen getting about on the substrate.

One of my usual solid coloured girls, it might also pay to take notice how the girls change colouration in relation to being berried with eggs and soon to hatch shrimplets

And the zebra patterned ones

Maybe with a breeding experiment in "setting" certain colourations in chameleons you will need to also play with the darkness of the water eg low light, tannin stained. The darkness of the substrate eg white sand vs black sand. Plantings heavily planted vs minimal plants. I suspect that eventually you will find a combo that forces the shrimp to adopt the pattern that you like best, but if they get moved to a different tank they would quickly change their markings and colours again to suit (in their opinion) the new surrounds.

I agree. Dave's notes seem to indicate that the black/white patterns tend to occur when the shrimp are caught from leafy habitats, and other colours dominate elsewhere. Just really don't have the space or time to dedicate to testing this.

      Thats a great photo, beautiful blue bolt, I hope it survived the molt without dropping the eggs! I think I can just about see some black dots (eyes) on the central egg but can't be 100% sure. I used to (and plan to again) do weekly water change of 10-15% but if you do too large or quick (not drip in new water) that would likely trigger a molt. What KH are they in, my new setup is sitting at (and refusing to budge) KH 3 and PH 7.5 so I may have to settle for neocaridina shrimp this time as opposed to the caridina I want, though not looking/deciding just yet, give the tank a bit more of a run in! Tap water here starts at kH 14, tds 320, when filtered goes to KH 0 and PH 6 but when put in the tank keeps going to KH3 and PH 7.5 despite 3 x 50% water changes???? You may be at 'maximum capacity' with only 20L tank especially if the tank is a cube type rather than shallow type?

      Right now this tank only has blue bolts and golden bee (red bolts?).  The eggs start off all brown, but at the end, I notice that some are kind of a clear pink-ish color.  So I don't know if that is the egg color of dud or golden bee.  Picture of shrimp only about half hour before molting. The water is always RO + remineralizer, so it should be ok. The tank seems to still be on a "good streak" ever since I started the regimen of weekly water change, monthly gravel vac and plant trim.  The point being to keep the amount of waste low and removing moss / floating plants so that the nitrates go towards growing algae.  At one point, I had three berried females, but only netted about half dozen babies by the end, due to this early molting problem.  There might be about 30-40 shrimp total in 5 gallons, but still very few full-sized adults.

      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.
