Well, despite my best efforts, I've now lost both males... Got the diamox and needles. No signs of air in pouch for at least three weeks before they died. Our AC went out about a month ago, and one of the males got pop eye. Removed him to a hospital tank (got AC fixed, too, which seems to have been the cause) and his eyes returned to normal within a week. Two weeks later everyone seemed back to normal, except that the pop eye male wasn't eating well. Had a friend feeding them over Easter. Sat at 6:30 all were eating. Easter Sunday at 2:30 when we got home, the male that had been very active and eating well (nice looking belly) was floating in an upright orientation, but dead. Hit fins seemed to be rotting from the top to the base. Pouch was very pinched. Three days later, the other male (the one that had been having babies consistently) was laying dead on the sand... Both females appear to be fine, but so did the males prior to their deaths. Having a hard time knowing that two previously healthy males died under my care... Should I get the females out, too, and maybe give diamox baths? Worried about a potential bacterial issue. Does that make sense? They actively feed every time I feed (even the one female who used to only hang out on power cords within 1/8" of the water surface-did that for the people I bought her from, too).
