Do catfish have a menstrual cycle?

Answer by  Bob2476 (169)

No catfish do not have a menstrual cycle because they do not have a uterus. They lay eggs. They do not have live birth. They have no need to menstruate.

I believe catfish do have a menstrual cycle, but your best bet is to catch a female (unless it's an aquarium catfish) and put her in a fair sized tank based on her size, and find out for yourself, or try to research the subject..
