lately my female spotted gourami has been a bit testy with my male
Dwarf Gourami who has become more playful than usual recently. They chase eachother, swim together, and eat together with no aggression. But sometimes when my male chases her she becomes annoyed and nips him and swims away... he doesnt appear to care when she does this... he'll just leave her alone after that usually.
But today i woke up and saw a small nic taken out of his bottom fin!

He was acting fine so i dont know if it hurts... but he was swimming with her just fine. Anyways... I decided to take her out of the tank with him and put her in with my two honey gouramis for now... they seem to just leave her alone and vice versa.
Now my male is alone in his 15 gal :( ... i put some melafix in there becuz that seems to work wonders for my older betta who's fins someimtes get a little raggity at the ends.
I just want to know... do you think my male gourami should be ok? And will that part of his fin grow back? And if it should... how long does that normally take.
Sorry for all the questions
