Gastromyzon cheni breeding behaviour (PICS)
Posted: Mon Sep 18, 2006 9:11 pm
My Pseudogastromyzon cheni have been pretty lively in the last couple of days, with some obviously sexually active males in evidence. This guy has very prominent nasal tubercules and you can see his dorsal is split just behind the front rays. Probably from fighting.


Big nose armour

When you mess around in an editing program, you can really see how these guys are armoured.

Anyhow, this particular male just looks the part, whereas this guy below seems to be getting the girls.

He's been digging spawning pits all over the tank.


............and leading ladies to see his etchings. Note the difference in colour contrast between the male's colouring and the female's.


Sometimes he gets very flirtatious!

She looks as though she's saying, "What the hell was that?" Note that she has nasal tubercules, but nowhere near as large or numerous as the male.

I did see one instance of the pair sliding backwards off a rock in turn, but as usual they decided to do it the OTHER side of the rock from my vantage point. Of course, with the other fish in the tank, the chances of babies surviving are virtually nil
