I was wondering what other type of fish would go peacefully in my black ghost knife tank im getting the baby ghost on friday and he has to be in a 20g tank for a coupple of weeks untill i get the 55g tank and get the cycle started. I was thinking of putting in a electric yellow cichlid and a zebra pleco becuse of the colors but are unsure if they would be a good pick. Ive asked a couple fish stores but I dont know of there being honest or if they just want to sell me a fish. Any advise would be great. Thanks.
