I never said anywhere about mixing Trophs. I said I have multiple colonies......each in 75 gallon tanks, not together.
Also I have over 60 right now in a 75 that I just imported and I have no losses.
I don't necessarily recommend it for people, but if your experienced you can do it.
I have 23 in my 75. 2 spathodus that produce fry every two months like clockwork, 1 eretmodus, 20 lupotas and 3 duboisis I threw in because I like the way they look as babies. The lupotas are breeding now and I have some fry running around. I've got a 150 sitting around empty, I think I'll go with mpulugu next.
Never seen Ujiji with that prominant striping before, nice fish, look like juvies with that striping. I disagree with that many in a 75 but, to each his own.
