I bought an albino pacman frog for me and my girlfriends first pet i love him. Im really not sure what i need to do for him though. the pat person said put moss in his cage but i read not to do so, so i changed it to the cocnut fiber. At first he was eating alot, not a single cricket went bye without him eating it. but after i moved him into a bigger tank (just cause i had it) he kinda quit eating he ate one big cricket and never ate since... that was 2 days ago. The tank is pretty big its a 25 gallon tank but i put a divider in it to make it smaller. Also do i need to be giving the crickets vitamins because the store gives them vitamins all the time so im not to sure if i will over do it. please if you have any advice on what i should do about him eating please help me, im open for all suggestions.

Thanks
