Please help me. I have a beautiful double tail Betta I bought from PetSmart about 2 years ago.
I keep him in a 5 gallon tank that uses a charcoal filter system. I keep the tank between 78-81 consistently. I do 75% water changes every 1-2 weeks. I feed him pellets and freeze dried brine.
Last Friday, I noticed he had a bulge on his side and he was much more inactive than usual. I researched on this forum. I did water changes, I did an Epsom salt bath. I stopped feeding him and then only fed him a bit of boiled pea on Wednesday.
I thought I overfed him and he would get better. He's not.
Wednesday I went to the pet store and got him these Marineland ALL IN ONE remedy pills. I took out the filter and put one in his tank each day. I changed about 25% of the water Wednesday. I tested the water: No ammonia, no nitrates, but hard water.
I have given him the rest of the pea. He ate some and left the rest. He is floating on his side on the top of the tank yesterday and today. He barely swims now.
All through this I feel horrible and helpless, and he was still swimming over to me and my finger on the glass until today.
I had hope he would make it until today. He is not outwardly struggling, but pretty lifeless.
Anything else I can try? Please, anything you can think of. Thank you.
