Hi I just added a Senegal Bichir to my discus tank, which is 75 gal. bow front. My discus are 7 large adults and everyone including the Bichir gets along fine, he has lots of rocks and drift wood to hide in if he wants. I feed my discus a balance meals of pellet food in the morning, and bloodworms in the evening. Through out the day I keep feeder white cloulds for them to have some fun chasing thier food. I know all the above is fine for the S. Bichir but I read that if you feed him Beef Heart he will grow faster. He is now about 5 inches. My only concern about beef heart is that it contains Thiaminase, which is an enzyme that destroys vitamin B in fish. I was wondering since S. Bichir is a primitive fish will feeding it beef heart over a long period of time affect its health?
