Best Treatment For

[newfishaddict]

I have an angelfish (Pterophyllum scalare), It is about 12 months old and 7-8 inches high. This fish has fin rot on its caudal fin. I have been carefully observing the fin rot for about a month, I have not treated this fish because the fin rot was very minor and I hoped that very regular water changes might help the fish fight off the bacteria on its own.

During the past month the fin rot almost disappeared at one point but now it is back, and back even more, so I have decided I need to treat the fish soon.

The angelfish is in a 29g tank with live plants , co2 via DIY, with 6 corries , 3 platies, and one bloodfin tetra. Ammonia nitrite not detectable, nitrate is usually 8-12ppm but it is likely 0-2 ppm now as I am waiting for my potassium nitrate in the mail, Ph = 7.0-7.2, temp = 25.8 C.

How should I treat this fish?

I know about salt baths but I don’t like the idea of netting this delicate fish….
I know I could add salt to the tank, I know corries don’t like salt but I have read that for a short treatment it is ok…
I also have tetracycline and erythromycin (the tetrac. Is in powder form and much easier for me to use),

What is the best treatment?

Note: my quarantine tank is full of fry now.....so it is not available

Maracyn one, if you could of issolated the fish i would say tetracycline, but don't want that in the tank as it will wipe some of he bacteria off in the filter.

Yes , one thing I have considered: taking all the other fish out of the tank except the angel, and treating with tetrac.....what do you think of that? I figure with only one fish in the 29g that I can keep up with daily water changes in case the bio-filter is negatively impacted......

If the finrot is not really to bad at the moment i would go with the maracyn.

Taken off the board.

Fin rot

Signs: Fin rot often begins with red streaks in the fins that are soon followed by abnormal lightening of the edge of the fin and then a fraying or rotting of the fin membrane and edges. This infection can lead to a complete rotting of the fin and can spread to the body and lead to death.


Transmission: The bacteria can be transmitted through the water from open ulcers, feces of infected fish, or through the consumption of infected, dead or dying fish in the tank.

Predisposing factors: This disease is not highly contagious, however it is often associated with poorly kept or dirty tanks with poor water quality. Any dead fish should quickly be removed and disposed of. Diseased live fish should be removed to a treatment tank.

Treatment: The antibiotics kanamycin or erythromycin are sometimes successful. All infected fish should be handled with care to prevent transmission to humans through open wounds or cuts
