If you didn't know my two Betta fish Chuck and Harold had SBD (swim bladder disorder). I had acquired them from my sister's science experiment, where they weren't fed in over 8 months. So they had SBD and I had left for 2 days for my horse show. I fasted Harold for around 5 days and I have been fasting Chuck and treating him with espom salts. I put Chuck in a 1/2 gallon to make dosing easier. Harold is in a 10 gallon. They are both heated and the 10 gallon is filtered. I do a 100% water change in the 1/2 gallon each day and 10% each day and 40% each week in the 10 gallon. Harold is all better even without treatment. :) But Chuck hasn't shown any improvement. I was putting 1/2 a tsp in the water but I upped it to 1 whole tsp. Is there anything I can do?
