Re: [Killietalk] Food quality and egg production

["Robert Goldstein" <rgoldstein at rjgacarolina_com>]

That might be the secondary question. It's hard to measure increased egg 
production in killies, since so much of it is normally done in bursts. With 
things like catfish and tetras, etc., high quality live foods (blackworms, 
white worms, etc.) usually brings about spawning by causing ovarian eggs to 
rapidly ripen (it always takes at least a couple of days, but usually you 
can expect results within two weeks). Now to address the more important 
issue, and this is something Martin Moe described years ago in relation to 
clownfish. If you greatly increase the nutrition of the adults (he added 
fresh frozen shrimp to the diet, and other sources of rich oils), the 
survival rate of the babies goes way up. That I think is the real benefit of 
a good diet for the adult fish. By good diet I mean live food primarily (but 
not BBS), frozen food secondarily (good stuff like shrimp and beef heart), 
and an end to reliance on cans of flakes.
