Finally, last night Cuervo the GT ate! I had tried feeding him some pellets, but he wanted nothing to do with them. So I got a decent sized chunk of frozen brine shrimp and fed him that and he PIGGED OUT!!! Later I put in a couple of pellets and he ate a few of those too. Again this morning with the shrimp and this evening I fed him some frozen blood worms.
Its so good to see him acting like his old self again!
Thank you everyone so much for all the great advice and support I got here! I really appreciate it!
