Well firstly

to TONMO.com.
I would really like to know where you got the cuttle

, they're really hard to find now...
As to the problem, what do you feed your cuttle, it could be something it just doesn't like. I used to feed mine pieces of cod but it didn't really like it, after awhile it would just grab the fish and spit it out without taking a bite.
Btw- got any pics you coculd share?
