right now i have a 55 gallon community tank with... 2 Firemouth Cichlids 4 Giant Danios 6 Tiger Barbs 1 Rainbow Shark 1 Rubbernose Pleco i have really, really been wanting a tiger oscar, and have been thinking for a long time about having another tank. so here's what i have been thinking of doing.. setting up a 20 gallon long for the TB's, Danios and Rainbow. i know it's a bit overstocked but i think it would be alright since it's 30" long. for the 55 i'd like to add 1 tiger oscar and keep it with my 2 firemouths, which are right now about 3.5" long. i really don't want to have just 1 fish in the 55. so it would be two tanks... 55: 1 Tiger Oscar, 2 Firemouth Cichlids 20L: 4 Giant Danios, 6 Tiger Barbs, 1 Rainbow Shark thoughts?
