Yes in under right conditions but I dont know about your present tankmates in that tank. Dont you need to worry about your baby sunfish and the fish you have right now?
Avoid convicts and jewel cichlids as most lfs wont take the fry into.
Rosy Red minnows are easy to breed, just add the flower pots and water to the tank. But the negative is that most egglaying fry are far smaller and need special foods. Most fry will get eaten by their own parents. You need to get a growout tank for these fry, but im sure that you need to ask your mom first to get another tank.
