Damn Gulpers

[Miguel]

How do you distinguish sexes in Gulpers?

No i had 3 males and 1 female but just picked up four more so know i have 4 males and 4 females. I can't wait to get a litter of gulpers someday.

These catfish are sexually dimorphic. When mature, males will have the first few rays of their anal fin fused together to form an organ used to internally fertilize the female. PlanetCatfish calls it a urinogenital organ. Female gulpers do not develop this.
