I have a 100 gallon aquarium with a 2 year old domestic hybrid discus a pair of angels and a school of cardinals. 3 months ago I was offered a wild green discus a a "rescue". The previous owner had "him" for 8 months and was feeding frozen blood worms. He claimed that they (he originally had 2 and subsequently lost 1) were dewormed and quarantined. The fish was "rail thin" when I got him. I didn't have a quarantine tank and do not have a hospital tank, so in he went into the display. He colored up immediately, seemed attentive and was even chasing the angel pair around. He didn't eat however. He would watch the food go down and inspected it. Once in a while I would see him picking at the driftwood. Two months went by and all of a sudden he started eating. He doesn't want anything to do with FBW, but he started eating frozen brine shrimp voraciously. Next thing he accepted was FD tubifex, FD blackworms and finally my beef heart mix. I was so happy that he had turned the corner and was looking forward to him putting on weight. Sometime last week, he stopped eating altogether. Still showing aggression towards the angels but does not come to the front at feeding and does not even look at food. My other fish in the tank are acting and eating normally. Any thoughts would be appreciated.
