Earlier you posted these all as begginer fish?Surely you would know something about them as to if you could keep them .As others have said it depends on the sexes (if the firemouths, convicts or oscars breed all hell would break loose) and if the oscar decides that he doesn't want to eat the gold rams for a snack then it will be ok, however my oscar has a go at eating anything that will fit in his mouth.im gettin a 50 gal or 46 gal bf. so how this stock 2 oscars, 2 firemouths, 2 convicts and 2 golden rams.
Yes, if none of them bred and you supplied good filtration regular water changes, plus sufficient hiding for the rams, still not sure a ram could live with either a oscar or a convict.That will set you back say atleast edit -£300.00, unless you get a complete bargain.hopw abou a 120 gal
