hi, was wondering around the pet shop and spoted this little creature. as i was not really planned to buy any fish i didnt check info. so i start asking shopkeeper about it. he said hes got him self 2 of them and they are really good algae eaters and good with community tank...bought it...2 months was ok...it start growing...and now i have a terrorist in my tank, he keeps chasing fishes especially gouramis(now start to rip scales off them). well i done research and got questions, some info says they are friendly some say its agressors. in another shop i ask info, they said they are really peasfull, and they got them in every screen tank...so is it just mine like that, or its the species?
