So, I got Caesar on Friday and noticed then that one of his fins was looking weird. I know it's gotten worse because more of his fin is red, ratty, and transparent looking (although it's not horrible looking....maybe a mild case?). Also, his other fins are torn here and there but there is no sign of infection.....so yesterday I went out and bought him "Bettafix" for what I think is fin rot. I changed his tank yesterday and gave him a dose.
So my question is, how often should I change his tank while he's on this med? and what percentage? Keep in mind I don't have a filter
On the bottle of the "Bettafix" it says to give a dose daily for 7 days and when that's up, change his tank then.....the pet store people say to change his tank weekly and by 50% (btw my tank is a 2.5 gallon) normally if he was perfectly fine.
By looking around the internet, there's a lot of different opinions, so its very confusing D: This place seems the best, so I ask, please help! (and sorry for such a long post)
