I don't know a whole lot about africans... it's my fiance's tank. A female rusty has had eggs in her mouth for about three days now. She's in a tank with a lot of other africans. Should we remove her to her own tank? If so, when? We have an extra tank that's been up & running & cycled for a while now with a sponge filter. We usually use it for breeding livebearers for feeders.
