Diego, I'm pleased you have found us here, thanks for the links you sent a while back.
Sounds like your roof top breeding is going well this year?
The sanke I used for this spawning is very special and not the same one as last year. She is from Momotaro and hope to produce a few reasonable keepers from her. My mud pond size is a compromise, as space is not unlimited. Using big females leads to problems with numbers. This leaves me with small fry for the first cull, then they have to play catch-up.
Maurice.
