I moved by black skirt tetras into my 50gal and soon saw that two of them have tiny cotton-ball tufts on their tail fins. (They were very nippy in my 29gal and they seem calmer in the 50. But the point of that is that I think that where they've been nipping at each other, they have gotten a little bit of fungus, I have been keeping the nitrates at about 5 to 10 in the 29, and I've been monitoring the ph and other parameters in that tank pretty closely, mainly because of the nipping, since I know that poor water conditions would most likely lead to fin rot where they've nipped each other. I had six, and bought two more large-ish ones to try and change their behavior a little, and I think it really did help. However.........)
When I saw the fungus, I added some salt (tsp per gal) to the 50. My qt tank is currently occupied by my new opaline gourami, so I didn't take them out of the 50. My question has to do with the best way to treat the fungus. I am thinking pimafix and melafix. I also emptied my 20 gal, putting the pg guppies into the 29 that the black skirts were in, along with the white clouds that were in the 50. (playing musical tanks here) So, now I could qt them if need be. I haven't bought the pimafix yet. I saw the fungus yesterday and began researching then and added the salt.
What do you think? What would you do? What has worked the best for you in treating fungus in the past? Would you treat the whole tank since I already plunked the fish in, or qt just the ones that have any spot on them?
(As far as using any kind of med that could kill my bacteria, I have enough tanks that I could transfer enough bacteria back to just have a little hiccup in the cycle. Plus, I have these two bags of gravel that I keep in the media space of a couple of my filters just for such an occasion; they stay nice and yucky, perfect to transfer to a new tank. :D )

Thanks in advance for any and all input.

I would try the Pimafix/Melafix first. It's very gentle, and it shouldn't harm other occupants, if you want to treat the main tank. However, as they're mild medications, you might find that it isn't strong enough. Give it a few days, and if the infection seems to be getting worse, you'll need to switch to something stronger (antibiotic). Not all antibiotics will damage your bio-filter, but some will. Generally, it's only a disturbance of the bio-filter, not an outright wipe-out of it. If you treat with antibiotics, it's a good idea to monitor the ammonia/nitrites, just in case there's a spike.

Many of the commercially available antibiotics will work on this kind of an infection. Look for one that has the symptoms on the packet, and follow the directions, and you should be OK.
