I wish I had known they were tasty to eat. Back in the late 80s-90s I bought 2 African snake heads that were about 1 1/2" long. Things grew at an insane speed starting out eating brine shrimp then guppies then small gold fish. Went from a 20 gallon tank to a 45 and then a 150 gallon tank. Was dumb enough to keep trying to put other fish in with them that were 4 times their size but they grow so fast and eat so much that they ended up being the sole survivors in the tank. In the end I was ordering jumbo goldfish that were about a foot long to feed them. They ate frogs, lizards, mice, rats, anything you dropped in. And don't put your fingers in either cause I guys they are on the menu also. Many of my friends found that out the hard way. Finally put them in a big cooler and tried to find a home for them. Thing lived in a cooler of water in my garage for 3 months. No filter just a bubbler. Then my girlfriends friends boyfriend said he would fit in nice in his huge tank with his "nasty" African cichlids(LMAO). A month later I saw him and he only had the 2 snake heads left in the tank. Guess they had cichlid dinner. Things grew from guppies sized to about 28"-30" in a year and a half. Incredible.
