Wow, have a response thx guys for the input. I do feed a varied diet of pellets, flake, live brine, guppies, frozen blood worms, krill, crickets, and the food that i find my cichlids are most likely to get addicted to, some are already, are Hikari sinking carnivore pelllets! So I guess i should be alright then. I find I really dont have a problem with the noise, i think that the noise is naturally drowned out of my head because i've been putting up with it for so many years and the loose ones get hunted down by the beardie when i let her roam.
