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

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! 😞

      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.

      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!

      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
