I'm still using store bought stuff (cichlid & goldfish pellets and the flake I bought 5 months ago) so now my fish are fed about 50/50 on the mix and space filling pellets.
So far everything's lasted longer as a result of this protein rich stuff. One of the main things I like about it is knowing they'll get plenty of vegetable mater (I'm not housing any strick carnivours-except possibly the pikes...and snooks) and they seem to be doing fine.
