Clown Trigger Laying at Bottom

Hello,

I have a clown triggerfish that is laying on his side at the bottom of the tank. He is breathing regularly (not too fast) and every now and then he will raise his trigger or twitch. His eyes look good and his coloration looks ok as well. When I went to feed him I thought he may be sleeping but when I realized something was wrong I tried to move him and he sort of just stayed laying on his side at the bottom. He made very little attempt to move.

My wife and I think he may be suffering from dropsy as that is the closest thing I can find to the symptoms he is demonstrating. His abdomen looks somewhat bloated (he is a robust fish to begin with) so I would suspect this to be a swim bladder problem.

As a desperate attempt to help I have added Maracyn-2 to the quarantine tank I have him in - (20 gallon plastic trash can only used for salt water making). The main tank has a maroon clown and a Diodon holocanthus in it and they seem fine, although I am going to check the nitrates to see if they are too high and what led to the Clown Fishes current condition. Temperature in the main tank is 76 F and the Salinity is 1.025.

I have been feeding the Clown triggerfish Mysis shrimp as of late, although I also feed him silversides every now and then. He eats the mysis at the surface of the tank. Maybe once a month I feed him crabs from the ocean that I catch by the beach. They are about the size of emerald crabs. I had worried maybe these crabs might have disease that they could bring to the tank, but I am not suspecting that here since I haven't fed him crabs in a month or so.

If there is anything I can do to help my fish please let me know. Another quick observation is that on two occasions I have noticed small bubbles coming from the triggerfish's anus which I had hoped would help him but thus far no improvement.

Thank you very much,

Charlie
