RAINBOW IRIDESCENT BLACK CHERRY SHRIMP IN MY TANK!!! HELP!


Liz

Recommended Posts

EMERGENCY!!! Hi, total newb here! I have what is effectively a skittles tank of different color cherry shrimp. I’m not a professional breeder by any means at all. I barely know a thing about neocaridina genetics. I just decided to add a few blue, red and yellow shrimp to my tank one day and let them have at it. They’ve since bred to about 50+ shrimp, lots of different colors, a few wilds, and tons of black! In fact ironically I was looking into my tank thinking I might trade some blacks for a few brighter colors when I saw this! 
Has this ever happened in anybody else’s tank before??! WTF I didn’t even know iridescent cherry shrimp were possible! How do I recreate this??!!! I need a ten gallon tank full of these guys!!!! What color combination can be bred to create this peacock?! Experienced breeders, please advise! I think this guy is third generation, but I’m not sure. 
Sorry the pics are so bad, my shrimp share a tank with lots of rambunctious male guppies and hornwort, this was the best I could get without reaching into the tank to move stuff and scaring him away. They don’t do him justice but rest assured he is stunning! He has a very nice rainbow shift on the carapace and a beautiful satiny purple iridescence to his tail. I managed to get some video of him too. I’ll try to embed it here in the replies.

You have created RGB shrimp!

Is there nothing safe from RGB.

I wonder if it's the reflection of the aquarium lights.

How you recreate more is anyone's guess.

Here’s some slightly better pics. And a video. 
I don’t think it’s the aquarium light since the one we have is white light only LED. Unless this shrimp’s exoskeleton is breaking down the colors in the white light… but then I guess it would still be iridescent...right? (Sorry I’m very blonde, almost failed junior high science)

White LED is made up of Red, Green, Blue colours.

Yes, that's what I mean. The shrimp's carapace is breaking the white LED lights down into the separate RGB colours. My black shrimps sometimes can show this rainbow colour as well, although not as striking as the one pictured above.

That’s awesome! I didn’t even know that was a thing!
Yes and these pics are terrible too! You should see him person! He looks like he’s coated in rainbow titanium!

It's a beauty that's for sure.

He really is gorgeous. I wish I knew who the parents were! ?

      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.

      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!
