well... I have literally more than 100 cherry shrimp in my breeder tank right now, and since I seem to have them surviving in my Hillstream tank, I'm going to start transferring more to that tank, out of the breeder tank...
my Cherry breeding colony has been doing great, , as I've pulled 3 times out of it so far... I gifted about 10, to a buddy with a 75 gallon tank, about 6 months ago, and he just sold his aquarium, and the new owner did't want the shrimp, so he ended up taking about 75 cherry shrimp of various sizes to a shop, that bought them from him...
my other colors of shrimp are doing well, but aren't as prolific, orange, yellow, and blue... with my cherries, I bought starter colonies from 2 different suppliers, hoping to get as large a gene poll as possible... I haven't done that yet, with the other colors, and I'm not really seeing a lot of babies, so I'll likely try ordering another breeding colony each, from a different supplier??? but, maybe the cherries are just more prolific???
