when you post a question like the one you posted the so called experts
come crawling out of the cracks to give advice.

i have been keeping fish for over 30 years and have had a small animal
practice for 20 years. i do know a little about fish and i will tell
you that giving your fish a live treat of brine shrimp or chopped worms
(or whatever) is O.K. i treat my 240 gallon malawi tank about once
every other week with live brine shrimp. in the wild they eat other
things besides algae. i have been to africa twice and actually watched
the fish in their natural habitat.

take everything you read here with a grain of salt.......
