definately add something in there. i haven't cycled anything that big before but i would imagine a month month and a half. completely cycled? or just to where you can add big fish? what do you want to keep in there?
yeah any cycler would get eaten pretty quick i'd do more of them but keep them smaller so they'll be sure to be eaten. you could always just throw a dozen rosies in there.
your fish sound pretty hardy so let it cycle for about a month or so and it should be good. any plant? they'll help.
Sorry I thought you were gonnna put LArge Fish in there and figured that eventually they would eat the Golds from 3-5" My bad... Your doin fine then.. Maybe add mroe The more the merrier
