Let me start by saying this is my first stingray. I know Retics aren't supposed to be for beginners but I'm 35 and been keeping fish since I was 15. So I bought a Retic about 2 and a half months ago. The guy I bought it from had it in a 75 gal. He estimated to have owned it about a year. This ray can't be more than 5 inch disc and maybe 9 inch tip to tail. I bought it because it ate like a champ. From the day I brought it home it ate like a PIG. It will only eat Mysis frozen shrimp for me so far. I feed him 2 cubes in the morning and 2 more at night. I can't figure out if this fish is stunted, parasites or way under fed? It looks healthy as ever to me. The poop looks normal and his stomach never looks empty. The age of this Stingray and it's size just don't add up to me. I'm open to all opinions and suggestions.
