he's easy to take pictures of he slowly glides around the tank but man when he wants to get movin he is real fast.he used to be nice i could pet him when i was cleaning the tank i used to be able to grab him and move him,but then one day while i was cleaning his tank he bit me,thank god he did not get a good grip.my thumb had 2 teeth marks and bled.scared me more then it hurt.he eat's of course g.f. feeders and rosies,earth worms,pinky mice,frogs, beef heart,jumbo cichlid pellets,and has eatin cheese and turkey and fish filet for treats.when i 1st got him i knew nothing about him he was about 3 inches.i had him in a tank with a bunch of fish well that tank ended up with a disease and i lost all my fish but him.well then i had him in the tank with 2 oscars,well he would try to eat them ,they ended up with alot of missing scales so he ended up in his own tank.other tank mates he ate or killed have been a couple cory catfish,plecostomus and some otocinculis.he also makes this loud nouse with his mouth,he will open it up and make like a coughing noise or a big thud.i was thinking it's like that crawfish that makes that loid noise with it's claw and it stun's the fish.all i know is when he passes on he will be mounted,and he will be replaced with another MR.GOBY(thats his name).thanks for reading,Nina
