Hi all. This is going to sound like a dumb post, and I have been at this for a long time, but I STILL don't know for sure how to maintain a quarantine tank for a sick fish. I've got a black skirt tetra who is not acting right, she's a little bloated and swimming wierd (kinda sideways), with a bit of fuzzy stuff around her mouth. I put her in the 5.5g QT because she's breathing heavily and the other skirts were nipping her.
I think I am going to treat her with maracyn 2. Now, here's the maintenance question: the QT isn't filtered (but it does have an airstone/pump and heater). How much water will I want to change per day AND does this affect the dose of the maracyn I add each day?
It would great if anyone could help me...it's so silly that I still don't know how to do this, but I don't! I don't even know if I can save her, but I'd like to try and not have her swimming about in a completely skanky QT. Thank you!!
