In my nano desk tank I kept 2 endlers, one male dumbo guppy, and 3 female endlers. The point of this was to get off spring that look like the males, went great for awhile until one day I woke up and my dumbo has been torn to shreds. His tail was missing chunks, his dorsal fin had a hole, and it looks like the top half of the base on his right side was torn as well. He is now in the tank with a scarlet badis (have had it for a very long time, for sure not the culprit ), shrimps, and snails. He is healing very well, only a small bit turned black from rot but I cleared that up in a day. But his pectoral fin doesn't seem to be improving. Though it has only been 2 days.
He is plenty active, still uses the fin but not as much as left side. Still eating good, practically healthy except his fin. He's super hardy and will put up a good fight against anything so... really any treatment would be good.
Does anybody know if it will reconnect with the fin? or regrow? or heal back to what it once was?
