I'm new to this forum and I've have been wondering this for the longest. I have a Red Cap Oranda named Lil Red and I've had him for almost a year now (got him Oct. 3, 15') and he hasn't grown much at all. I did some research before I got him and bought a 30g tank and necessary equipment so it's not like he was kept in a tiny bowl. Around June I downsized his tank to a 20g. I feed him once a day sometimes more. I give him spinach at least 4 times a week. Would anyone might know why he hasn't grown? I want him to get big and chunky like orandas should be.
Thanks for reading,
