i am a newbie at keeping community (peaceful non cichlid) fish and i am growing out a small juvenile common oscar(spike) in my 29 gallon community tank. his mates are a moonlight gourami about 4" , 2 tiger barbs, 1 cory cat, 1 small tinfoil barb, and 1 black skirted tetra. my question hes doing very well not nippy at all and quite peaceful in his current setting. but i am worried that when he moves on up with the big boys he may not fair so well. do u guys feel i mad a mistake about keeping him in a community tank with all these non aggressive fish?
