Hey, im my tank i currently have a dwarf gourami, cory cat and a female guppy, i would like to get 1-2 more gouramis, and 2 clown loaches. Could i also get a cichlid? Maybe one of the ones that only grows to about 4-6 inches. BTW i have a 20 gal tank. I also have a 5 gal that i could put the guppy in if the cichlid might eat it. I only have access to Petco cause my parents won't drive me anywhere else (LOL). They have a few ones there that only grow to like 4-6in it says but the fish guy said that it would eat everything in my tank. Want your opinions! Thanks, any other questions, please ask!
