Well, now I need some help. The little guy isn't eating much for the last week. His main diet is live blackworms. I feed chopped shrimp and FD krill as well. He won't even look at the krill and shrimp now, and is barely eating the worms. Maybe 5-6 a day total. He used to have a bulging gut, now not at all and is looking kind of thin from above. I have been doing daily 10% waterchanges since this started. I raised the temp to 84. He grew about an inch real fast, but that won't continue at this rate. I also added some rocksalt. No new tankmates. Nothing has changed. I did notice that he takes a long time to choke down the small amount of food he is eating. My concern is that it may be an internal deformity that is making it hard to eat. Any thoughts?
