I bought some uaru A. that had been savaged by beiing put into the wrong tank in the shop. i decided to rescue them to give them a fighting chance. they had no tails left, just little stumps, and the rest of their fins were mangled.
i dosed them for a couple of months with melafix, no infection occurred despite the severity of the injuries, and fins showed growth and improvement in a week or two.
for other split fins and scrapes ive dealt with they have healed really quick when using melafix, other injuries ive thought not in need of treatment healed far more slowly.
i cant honestly tell you if it was the melafix or just good water quality or both but it seemed to do the job in the severe case. this was my first severe injury case ive dealt with so it may have been luck but i used melafix and i would again from that experience.
