A few of the fish I collected last week have developed fin rot. One has small white fungus looking patched on the fin, while the other have a faint white outline to the fin. Other fish in the tank appear the be fine. The tank is 30g cube and the water quality is 0 ammonia 0 nitrite and <5ppm nitrate. The tank has about 1 tbs salt be 10 gallons. The fish seem to be feeding ok. What is the best course of action?

The only thing I've ever used successfully for something like this is Maracyn Plus (not the regular Maracyn). It supposedly has some way of sticking to the outside of the fish so it can better deliver the antibiotics.

Chip clued me in once that it isn't really a fungus, but some sort of bacterium. I forget which kind. His trick of putting salt in the collection water does seem to help prevent it.

I'll get some Maracyn Plus and see how it work. I used about 2tbs per 5 gallons in the transport water and most of the fish look great. I think the water down here is rough on the fish, although the water in this tank is run through a large filter and aged before it enters the tank. Thanks for the advice.

SALT SALT and more salt! Keep it in the quarantine tank at home as well, in fact I keep it in all my tanks all of the time.

Roughly how much salt per gallon?

At least a tablespoon per five. I usually keep mine closer to 1.5 tablespoons per five. If fin rot starts, often the salt alone will not halt its progression. So some harder drugs might help out, but you should try to sepatate the affected fish and treat them alone, as there is no reason to pump harsh chemicals into healthy fish. Melafix may also be of some help, as fin rot is actually a bacteria, but I have mixed feeling about the product. I believe it is helpful in mild bacterial infections, but less so when it is more advanced. Be forwarned, that finrot once it gets a good hold, moves very fast, can move from the caudal peduncle up to the dorsal area in 24 hours.

A few of my fish have a white spot on the tail....is it fin rot? its just a tiny white spot...some not even at the end of the caudal...one is on the anal fin...is this ich? or the starting of ich? or does ich have to be like all over the fish?

on a side note...The saltwater dip worked on one of my fish...the fin rot is gone...but the other day I might have had it in too long like 30mins (4tsp salt to one gal water)....and one of its eyes went cloudy...not sure if it bumped against something...but now its ok...

Hows the finrot coming? I was wondering if just the salt cleared it up or did you have to use some medication.

This doesn't have anything to do with fin rot, but I had a bluegill that had a large infected eye for about a month or so. I just recently moved into a new place and around the same time read about how adding some salt to a fresh water aquarium was beneficial to the fish. I added 2 tablespoons of salt to my 20 gallon tank, and within a day the bluegills eye went back to normal.

Pretty Impresive.
