wow , thanks i just thought that he was not ready to eat, ive tryed sinking and floating pellets and frozen blood worms, he has been really active so i just thought that he was still not use to his new home, i got 15 guppies and he ate all of them in 2 seconds , how often should i feed him the guppies? sorry for the stupidity the guy at the pet store said he will be fine with pellets, but im dum for listening to him they had it in a tank full of some other fish.
