i have one just like it and ever since i got him about 3 4 months ago i havnt seen him eat, he is getting very skinny i think once he runs out of fat in his tail hes gonna die. i have tried everything, spent alot of money trying to get him to eat. no luck. he has a big bump on his head so i thinking it has to have some thing to with that. it sucks to bc i have never seen him do anything, ya i got sold a sick lungfish
