I have about 16 fish in a 75, 14 of which are Mbuna. I have had three batches of fry 10 hybrid red zebra / auratus fry, 11 demasoni fry (from two small females), and just now I stripped 17 yellow labs from their mom. My demasoni female is holding again she grew some so is probably holding about 10 (I'm going to strip her next week) and I have a good sized pearl mutt holding for the first time. She will probably have 10-15 fry. I am going to keep some of the yellow labs and all of the pearl mutts but am not sure what to do with the rest. Do most pet stores buy 1-2 juvies? If anyone lives in north jersey and wants some fry let me know and I'll give you some in a few weeks. Otherwise I may cull half of the hybrids as they are not attractive and just dump the rest into my 75. I'll have about 50 fish in there.
