After trying everything I could think of and everything fishlore friends suggested, I had to relocate Ice Blue. I couldn't find him a mate and he had taken over all but about 2 inches of the 55g. None of the other fish could swim and one of the msobo ended up suspiciously, umm, dead. Ice Blue, pretty as he is, is now at Petland. They have already sold the other 2 I took them.
The tank is now fairly peaceful with 2 msobos (lost the one the other day) and 6 greshakei juvies. I am going to add 2 more msobo females when I find them and wait to see what the greshakei turn out to be (m/f?). I may add a few something else but don't know what...
Since Ice Blue is gone, had to change my sig pix
Thanks for all the help.
