MTM_F-;2090898; said:I think I'd probably move him out at the 8 inch mark...and I'd do 50% (maybe a little less) water changes every week, just like on our other tanks. I've never had any non african cichlid before, so maybe I'll give it a shot... If he does grow too fast, he can just be put in a bigger tank back home. College is only 45 minutes from my home, so I could even continue to care for him.
I'm still thinking that an AC110 might be too much water movement? 500 gallons per hour, right? Would that be too turbulent?
I still say a ac110 is overkill for a 20gallon. A 8" midas in a 20gallon would be ridiculous. If you kept him in there until the 4-5" mark that would be fine but 8" is too big. Did you think about the fact that if you keep him solo for 4-5 months and try to put him with another fish its nots going to work, regardless of tank size.
