Indigo is my daughter's betta. He was already the biggest one we had when we brought him home and we've had him for a year and change now.
I noticed about a week and a half ago that he was looking *very* bloated. I checked her food jar and it was almost empty. (This is a cautionary tale, don't just assume it's all good when the child says Yes They Fed The Fish)
Indigo has been on a strict diet of two pellets a day but he doesn't seem to be de-bloating. Two days ago, I decided it wouldn't hurt to see if we can help it along. When I went to change the water, I discovered the heater plug had gotten knocked loose, and the temp was down to 72. He's now in 2.5G treated with 1 tablespoon of Epsom Salt, and I've brought the temp gradually up to 78. Last night I soaked a couple of FD daphnia and let him have that instead of pellets. I put a mirror in for him for a few minutes since there seems to be anecdotal evidence that a nice round of flaring can help pop out a poop. He flared and danced for about 20 seconds and then went and hid in the silk plant.
Other than the bloaty tummy, he acts normal. He has an appetite, he's built us a tiny bubble nest. He's been in the same tank for the last year, nothing new was introduced that might have given him parasites, though there's always that chance...
I could toss an IAL in. I have some. Since his behaviour is fine, I don't want to hit him with medicines if I don't have to. Am I doing the right things so far? Any other suggestions?
