I would fill out the tank info form, but this is affecting 3 different bettas in 3 totally separate tanks.
They all are at the temp 79F, one is in a 3 gal tank, one is in a 1 gal tank, and the last is in a half gallon bowl- he gets upset if I try to move him to a bigger space.
I've been feeding the same Top Fin betta pellet for a year now. Suddenly this week 3 of my bettas are bloated at the same time. I've never had any issues with this until now, and my other 6 are fine- I have too many fish
. I've tried fasting them, feeding less, and I tried salt treatment on the worst of the three. None of it seems to make a difference. I tried switching food but it didn't make a significant improvement.
I don't know for certain that they are in any way related, but it is an extremely odd coincidence considering I've never had any issues with bloat in the year since I started keeping bettas. The only one that seems very affected by this I suspect has other health issues and is older. He's the only one that was fully grown when I bought him, and I've had him about 3 months. If I feed him two tiny pellets, even though his stomach was normal size before, he swells up to the size of a pea. When I get him to flare to help him pass it, he expels a large amount of gas and sometimes poo that floats. Any suggestions about a course of action? Is this something that could just be worsening with age?
