I have a new 46 gallon bow front sunsun canister kind of a reparium setup except full of water with a planter box behind it. I got this tank specifically for pearl gouramis. don't know what else I wantI visited the fish store today and I'm thinking a pair of angels and maybe a pair of kribs along with a small shoal of dwarf neon rainbows. I like to have some cleanup crew in there have Cory's and plecos in a different tank so would be looking for something different. what do y'all think what about the number of pearl gouramis and male and female ratio?
