I have see pics of 24 baby caribe eating a once frozen mouse they ate it to the bone amazingly it did not make the water dirty beefheart, feeders, fresh fish, fresh meat, hamburger will make them grow like for some reason it worked for me but be careful don't feed the m alot of it they can die and it will mess up the water really bad and only feed them liek the extra lean kind don't only rely on the hamburger you must give them a varied diet
