I have a male Vieja Breidohri that i think is around 7 years old. He hasn't had much of an appetite lately but looks fine. I'm wondering how old these guys live to be? He seems kind of young to me but i'm starting to wonder if he's sick or maybe even dying. Does anyone have this fish and does anyone know how old they live in captivety? I want to treat him with meds but i have no idea what could be wrong with him. He's in a 90 gallon with a female Robertsoni, female HRP and female Tamasopoensis. I don't see any aggression at all in this tank.
