So, my RBTA has had its stomach(i'm presuming) sticking out like a white bubble for the past few weeks. Before that, I've never seen any sort of issue with it; just sits in his spot wafting in the current. He is still in the same spot, seems to look completely fine with the exception that its arms may be a little skinnier than they were pre bubble. I generally never spot feed it, but I've done so a few times since this issue has arose, but nothing changed. His routine is the same, hides behind the rocks at night, and returns to his perch when the lights come on. But his bubble/stomach has not retracted since it first appeared 3/4 weeks ago. Today his bubble is tauter and bigger than normal, so I snapped a pic and posted with the hopes of finding some guidance on this issue. Thanks in advance.
