wondering what the bare basics for a tank for a breeding pair of clowns is?? this isnt a display tank, just a breeding tank for the clowns. I guess what im asking is can you just use a bare bottem tank with a few tiles or something for them to lay eggs on. water, heater, pump, light.....and pretty much nothing else? The reason i ask is this is how i do freshwater egg layers using a piece of fake spawning grass or other species accepted spawning site then remove it to hatch. what type of system to commercial growers use? I could care less about the whole reef thing, its strictly the fish and reproducing them Im interested in....I gave up on tank decorations along time ago for my freshwater setups, but this is my first venture into saltwater species. BTW I have several tank options avalible from 29g to 55g.
