I heard that RBPs should not be fed every day. They should be fed every other day to make them aggressive. They say it makes them agressive cause they will be hungry and want to feed when they get the chance. I also heard to get some bloody liver and take the blood from the liver and drop some drops into the tank to make them smell it also to tease them but not to feed them. I should tease them for 2 days so they will became madand feed them the 3rd day. I heard this makes RBPs more aggressive. Is this true or BS?
