i got mine for 150USD , hes realy cool will eat out of my hand the first night I got him. his stomach gets huge when he eats. you can see the outline of the shrimp. mine wont eat the shrimp unless I peel the shell off
When I feed freshwater fish with sea food I always rinse it well so that I get rid of excess iodine that the freshwater fish are not used to. Dont know if you ever bother to do the same??
