I have a half moon betta... he is in a one gallon tank. his tail used to be pretty long and now its about 1/3 to 2/4's the size it used to be and his other fins are starting to disappear as well. I've been doing a 25% water change every day with a 50% change each weekend. I want to get meds for him but my father refuses to take me to get the meds... is there anything else i can do it keeps getting worse and i feel like a really bad caretaker. I've started doing two 50% water changes a week as of this week plus the 25% every day.
