Very interesting. The ones I have are supposedly F0, were sold to me as such by someone I trust to be telling the truth. I'd have supposed that they'd prefer something moving over flakes, but go figure. Maybe I should try blackworms??? I've used tubifex, but not for at least five years, and never with cichilds. Lately I've heard bad stuff about blackworms and tubifex with parasites. By flies do you mean fruitflies? I'm not sure these guys would eat off the surface, they wait for things to sink. BTW, what's a grindal worm, never used them before.
