All above advice is great but i strongly advice getting a sandy substrate , classic coral sand even. It brings out the true character in shell dwellers ie, robbing burrying shells , making sand mounds around there shells for homes and also for breeding. Most females will need to bury the shell untill only she can fit in it to protect her fry as they are not mouthbrooders
Look forward to the pics , Goldys get mean with other shellies
