Lovely shrimp, I had no luck with yellows and sadly it appears the few rili's I had have gone the same way.

Best of luck with your yellow rili project.

Great to see someone's selectively breeding them. I had a pair I tried to selective breed, without success, and the F2 were all rubbish...so I gave up :-( Keep up the great work :-)

These are gen 3 breeding about 50% rilli Have 30 odd girls and 10/12 boys to work with now just need to select separate and cull maybe 2 more gen should do it.

AS per blue project sorting has given me a 30+ strong colony of these.Hope the next gen is 80-90% rilli as this time it was 60-70%.

How does the Rilli gene work, i take it it would have to be a recessive mutation and that the solid yellow would dominate if cross breeding were to happen?

If that is the case could you cross in more solid yellow down the line and cross the F2 of the offspring back to rilli parent or rilli sibling to strenghten the yellow but keep the rill pattern?

Yes genetic floor have been breeding rilli to rilli to strengthen pattern and crossing back to solid yellow to get the yellow more solid.These are about 2 years of crossing back and forth and breeding around 90% true have 4or5 very nice girls now just hitting breeding age so fingers crossed not far from letting some of these get out for you guys

      Finally set up the 30L Shrimp Tank

      By sdlTBfanUK · Posted

      I have just done the planned weekly maintenance and 10% water change and everything 'seems' to be going very well, I saw 12 blue and 9 panda shrimps so am very happy about that as there are always some hiding (and they are small) so there must be more than that at this point. Early days yet (especially with the off parameters) with the blues only been in the tank for a week and the pandas for 2 weeks. Not seen any dead ones yet and the shrimp seem happy enough and beautiful colour and pattern, all small so must be young! Parameters were TDS 159, GH 7-8, KH 1-2, PH 7 yesterday so still a bit off the usual ideal! Hopefully these figures come down slowly in time, I used pure RO water for the water change so Tds should drop 10. I will get a different PH test kit with a narrower range/increments as the one I have measures in .5 increments over a wide range which is probably a bit much. I bought these shrimp because the sellers parameters (PH 6.8) were the closest to mine so hopefully it will work out long term. I changed my zerowater filter as well, as the old one was measuring TDS 6 so passed its best. I will definitely overnight drip acclimate shrimp in the future, not that I plan any more in the forseeable future. I will add/edit photo when available, hopefully later today.

      By sdlTBfanUK · Posted

      All done now, I drip acclimated 11 blue bolts and 6 blue steel overnight and they are now in the tank so now is just wait and see if this works. 28 shrimps have now been put in and I have yet to SEE a dead one so fingers crossed! A couple of pictures of some below; I don't plan on buying any more shrimp so plan this to be a blue shrimp tank, though if it doesn't work out I have seen some female bettas I would like, but hopefully the shrimps will work out. The water parameters are still the same as before, so a bit off! I need to sort out what foods and shrimp stuff I have in the drawers and cupboard tomorrow as it's been a while, hopefully I find a shrimp lolly so I can give them one/part of those tomorrow, and it may bring as many of the shrimps out as possible.  Fingers crossed everyone...........
