Cearbhaill,
I do have a little experience breeding tropical fish, but not much with cold water fish. At the present time I breed Angelfish and Betta. I have bred many different live bearers in the past. And I have just started to breed Cory Cats. My wife has a couple of Red Caps and would like to breed them.
I have checked out the site that you recommended and it is great.
Thank you,
Jim
