Will gourami's feelers grow back?

You may want to check in to this product called Melafix and it is a medication that helps heal wounds on fish.

Depends. If the feeler was broken in the middle, it will eventually grow back. If it was broken off really close to the body, it may not. I've had them lose all but about 1/4 inch and it grew back just fine. Keeping the water conditions tip top and feeding a healthy variety will do far more for the fish than any additive. The injury is unlikely to become infected, IME, simply because it is such a small wound that it closes quickly.

Warning, do not use Melafix or Bettafix on any kind of labyrynth fish including gouramis. The active ingredient will irratate the labyrynth organ and can cause death. There is an article on fishgeeks.com that tells you all about it. Go under the help forums and then go to anabantoids or bettas or gouramis, I can't remember exactly which one it is. Do take into consideration that some people have had different experiences with this product. I don't want to discourage you from using if you choose to, I just want you to know that there may be a risk involved. Good luck.

I've use Melafix-and Pimafix with my Gold Gouramis and Bettas without any issues as have many others. Unless there is a sign of infection clean water is the best thing for fish, so do regular, even extra water changes. If there are signs of infection then treat your fish with medication.

hope the same thing goes for one of my pictus catfish's feelers. (I bought him like that)
