Alright, a rundown on my sick swordtail. She had Ich 4 weeks ago. I treated the tank. She developed Columnaris 2.5 weeks ago. Was late on treatment. Treated, only to find the medication was expired. did several water changes and waited to see if the treatment would still work. Now shes got her fins clamped and is sitting on the bottom of the tank kind of flailing a bit. None of the other fish in the tank are ill. Whats happening? Should I just prepare to lose her?
