So, Altair's gotten his fins all raggedy (again), and this time it's definately fin rot.
I'm moving him to my hospital tank (again) and trying to decide if I"m going to treat with aquarium salt (again) and giving his main tank a thorough scrubbing(again), even though he got a water change not two days go.
What's really concerning me is how fast it's eaten away his fins, though. Last night before I went to bed, they were still in that halfway "is it/isn't it/are you getting your fins caught in the filter again fish it's on the lowest setting ISTG." state with some healthy regrowth from where he's been chewing on his tail, and this morning there's probably about a good centimeter of stringy finless rays and white bits.
So I guess my question is? This is fin rot, right? and am I treating it correctly? I know everyone says the best treatment is clean water and heat but the heater for the quarantine tank is trash, and the main tank's heater barely fits in the main tank let alone the tiny 1.5gal one, so should I treat with Aquarium salt, or can someone suggest a cheap, easy to find heater that will heat the water more than two degrees, or what should I do? how this one tiny fish manages to make me post in this particular board so many times a month is beyond me.
