My male carpintis today has been chasing the female and has her hanging out in the upper corner of the tank. All his fins are up and when ever she comes down he chases her back up. Is this normal? She is sitting up in the top corner, she ate when I fed them so should I separate or is this some type of mating behavior. I am ultimately worried about her well being, I rearranged the tank a bit but it made no difference.
