Hi,

One (at least) of my female chinese Cobitis has eggs in her belly. I've noticed that some females will be plumper, but so far I couldn't see the eggs. Today one female was in the front of the tank and with a loupe I could have a closer look. The pic isn't very good, but I hope you can see the same as I.

Looks like eggs to me. Do you have males Thomas? Beautifully marked fish!

Yes, not many, 4 males against 14 females /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Lucky guys! /cool.gif" style="vertical-align:middle" emoid="B)" border="0" alt="cool.gif" /> This looks promising Thomas. Do you know much about the life history of Cobitis spp.? I know the ones here in Spain are very much seasonal breeders spawning in late Spring and again in Autumn.

As I know the "german" Cobitis spawns only one times a year - late spring early summer. The spawning happens in shallow water.

My idea is to wait a few days (or weeks) and then beginning to reduce the water level and start to heat the tank a little bit.

Another idea is: Do nothing and hoping for the best... /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

I'm unsure /unsure.gif" style="vertical-align:middle" emoid=":unsure:" border="0" alt="unsure.gif" />

Very cute. /wub.gif" style="vertical-align:middle" emoid=":wub:" border="0" alt="wub.gif" /> Are they in an unheated tank at the moment?

Yes, another group of this species are outside in my mothers garden at 5°C at the moment. I have too much of them, so one group (8) is in my tank, and one group (10) is in a cement bucket (ø 60cm). Both works fine.

I reckon leaving the ones outside to it might work - it's what I do with the Aphanius. Just increase feeding at the right time and let nature do the rest! /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

I seem to remember a chap in England had some success when he brought his C.biwae indoors , he thought it was a little cold for them outside , when he put them in a unheated aquarium they spawned !
Good Luck /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" />
