I feel terrible! I think I may have really messed up. I got a new betta about 3 months ago and added a snail shortly after. He kept going after the snail, so I just added the snail in with my other betta and snail. This week I had the bright idea of feeding the two snails a chunk of an algae wafer because the tank was unusually clean. I noticed a couple hours later that Pory, my other betta, was HUGE and still eating algae wafer remnants. Now he is floating at the top of his tank and is starting to pinecone. I just watched him to see if the bloating would go down before treating him, but I am now just dosing with epsom salt. Poor guy has never been sick for the 2 years I have had him and now this. He is in a 2.5 gallon tank, with a heater, no filter and usually is fed pellets and bloodworms but is being fasted now. He has been in this set-up since I got him. Any advice is appreciated.
