I have had issues when I got a new tank, very foolish and amateur of me by over stocking the tank. My exisiting fan tails (3) from previous tank have ended up with shredded tails , and the black pop eye one's eye looked liked it had popped out. Unfortunately I killed 2 of them by way of toilet which I hear is cruel but I felt it was more cruel to leave them. The last fan tail has bad shredded fins and white spots. Over the last few days the white spots are more and more and it almost looks like a layer on the fins. It swims away from other fish who get close but then goes vertical with mouth at top of water and drifts around the tank only to swim away if any fish go near it.
I know I have made several rookie mistakes which won't happen again, however I have been treating the water on a 5 day course for fin rot and bacteria, the 5th day finished today but it hasn't got better, only worse.
All the little fish seem ok, bar 1 that has 1 white spot on it.
What do I do to make the best out of a bad situation, do I kill the last remaining fan tail as I don't think any chemical is working ?
Do I do a 1/4 water change every few days?
Can any one help with what to do? I know the mistakes I have made but keen to resolve it as best I can.
