I'm looking for some advice I have a blue spoted jawfish that I have had for 2 years. ( please don't ever buy one unless your experience with them. They are very hard to keep and not suitable for a reef tank.) I nursed this guy back from blue spoted jawfish disease so I'm really attacked to him. I had him in my 90 gallon reef for a year and a half but had to move I'm into a 20 gallon tank a few months ago. I made sure he has plenty of sand and rock to make hiding spots in. He was doing great for a while eating like pig but 2 weeks ago he started eating way less a bite or 2 and about a week ago he stopped eating. Yesterday he won't even come out of his burrow. I have tried Mysis shrimp krill, brine frozen brine live brine flake and pellets but he won't eat anything I even tried fresh scallops. I meditated his tank for 3 days with Erythromycin just to try. Can anyone offer any advice on 1 how to get him to eat 2 what might be wrong 3 how to possibly treat him. Any knowledge would be appreciated. I posted a few pictures of him i took yesterday .
