Anyone know how to tell the gender of Rubber Nosed Algea Eater?

Question

I'll be amazed if you can tell me under what conditions they breed. I think I have an idea, but I'm not sure.

Answer 1

The males have a wider head and larger pelvic fins usually. This can best be seen in a tank with quite a few individuals to compare.

Breeding has not been documented in an aquarium environment.

Here's a link with some more info on them

Hope that helps

Answer 2

if by rubber nosed algae eater you mean the rubbernose plec or "Chaetostoma", then sexing will be similar to most other plecs. The males have a somewhat larger and broader head, slimmer ventral sides and disproportionately large pelvic fins.

apparently there's not many reported cases of many Chaetostoma species breeding in captivity.

Answer 3

You can't tell the gender of egg laying fish unless they are one that the male is a different color than the female.
