I bought a small red white ryukin and I want it to grow big. I have a 50 gallon tank and it doesn't usually eat as fast like my other goldfish that I've had in the past all it really does is wait til I leave and eats the granules off the bottom. It just doesn't really seem that interested and eats off the bottom so idk if that's a problem. Also I want to name it but I don't know if it's male or female so if any of y'all know how to determine sex of goldfish that would help thanks.
