So this fin rot has been going on for far too long..
I have a 30 gallon tank stocked with currently 8 Tiger Barbs.
4 of them are fairly new to the tank.
1 of my barbs has fin rot that hasn't seem to heal. I've used treatments of Melafix which did not help. and I've used API's Triple Sulfa. His fins have been deteriorating for about a month now, but luckily he hasn't died yet. He almost has no fin left, but he is still able to swim at this point.
Now, I notice that another barb is starting to get fin rot!
I've been doing 40% water changes every 2-4 days.
What do you guys recommend?
It is a marineland tank with the bio-wheel filter
Water parameters were checked recently and came out to be normal.
I have been using API's Stress Coat as the water conditioner.
