Hi all, just got sent some pics of daydreams yellow rilli project, about time to cull and strengthen the colour.

Cheers mick 2014-04-14_14.57.45_zpsleoxukki.jpg2014-04-14_14.58.25_zpsh2oqgra3.jpg2014-04-14_14.56.20_zps0mcj6a09.jpg

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.

I'm in the same boat with yellows so just gave up on them lol.

Your rili's are looking good :) cant wait to see the results in a few gens time :)

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

      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!
