[Dentoid]

So sorry to hear this Ian. It seems to be a common occurance with this species. No one really knows why this happens. From all that I have read, about this species poor captivity record, it seems to point to intestinal parasites, and for what ever reason seems to overcome the fish in captivity. I have seen this more times than I want to say. The fish seems fine for a month or so, then stops eating and perishes quickly. It is best to purchase this species from a reputable source that quarantines them first and treats them for parasites while they are still eating. Or the hobbyist should QT them and treat them for intestinal parasites using frozen food soaked in praziquantel, metronidazole, and piperazine prior to releasing them into their main tank.

All you can do at this point is keep trying to feed him. Best of luck to you. Keep us posted.
