Hmm. If you do frequent water changes, and always siphon the tanks, everything should be fine. Since the cleaner the water is, the faster the healing process will be.
Sometimes, my dwarf male gouramis' feelers get nipped by my angels, but it seldom that my angels get into a fight with them... So when I always siphon the tank, and my plants helping to eat the waste the fishes leave, I usually find out that the feelers grow back very fast. Just like my
betta. It's had some fight with my yellow gourami a long time ago before I bought my angels, and everything.
So now, the fins are growing back centimeter by centimeter
