today i was so worried about B, that i went out and bought him a 1.5 gallon tank, with a filter and a light. its so beautiful, however recently he has developed white on his scales and also a little bit of swim bladder. i got some BettaFix for him as well. now, i was wondering how long should i keep him in his 2 liter tank with treatment before i move him to the bigger tank. i read somewhere that treating while using a filter is pointless because the filter absorbs the medication anyways. so what should i do?
