It seems strange the tail hasn't begun regenerating??? If I can remember Melafix is antibacterial. Perhaps whatever is eating away at the tail is fungal? But then again usually there is usually a woolly growth visible. I'm puzzled.
Kit Walker: The anti-bacterial 'claim' of Melafix is actually questionable. I've read reports on the web that it doesn't have much if any anti-bacterial properties.
I found it really funny too as there are no abnormal growth / texture around the missing part of the tail. My previous experience with Melafix had been excellent, damaged fins always starts regrowing after a few days.
My experience has been that the bacteria and Saprolegnia that are working together to produce "fin rot" have got their start where skin and fin parasites have created the opportunity.
Do you see a very fine white edge to the area where the fins are eroding? Saprolegnia.
I would combat this finrot with potassium permanganate treatments, following Dr. Erik Johnson's potassium permanganate regime described at www.koivet.com . You have to be very cautious with this stuff.
becareful when using certain anti bacterial meds, since some will kill off your bacteria bed. If you are using anti bacterial or fungal treatments i would recommend a Q tank.
wetmanNY: Now that you've mentioned it I 'think' I do see those very find white edges where the fins have eroded. It's extremely difficult to spot and I really have to look hard. Maybe it's my imagination?! Where would I get potassium permanganate from? The LFS? Sound't like someting that I'd use in a high school lab
valerie: Yes I do have a Q-Tank that I could use. Just don't want to catch him and put him in there yet. I'll wait till the weekend when I go to the LFS and get some meds.
