i am sad to hear about your betta and what you're going through. how has he been? what size tank is he in?
my guy is taking a while to recover too...... he's 1 so he's younger than your guy. my guy is in a five gallon currently. i asked about water changes in a thread i posted a while ago. sakura8 (do you know her?
) told me if the tank is bigger than 2gal, do 50% water changes once or twice a week with one additional 100% water change per week. feed him frozen foods to get protein. i tried feeding him pellets high in protein and once every two or three days feeding him frozen bloodworms, brine shrimp, and daphnia. although i have only been feeding him pellets lately because currently have a bad ankle/back injury. work injury.
i keep his temp 76 degrees and don't let it fluctuate. if you already have it, try using api stress coat......
man, probably overwhelming you with this msge. oh boy......
sakura8 has helped deal with my sick betta.
