Hey guys i bought i leopard puffer fish today i brought him home and set him up in his new home, hes doing just fine but i have a question about feeding him, ive never owned a puffer before so im kinda cluless the guy at the pet store gave me these worms that come in little cubes and told me to press them against the aquarium walls and the fish will eat it, sounded good to me so i bought the food for him/ her (by the way is there any way you can tell the sex?) and got home to try it out and whaddaya know, the little cubes dont stick to the walls, they stay on for like 3 seconds before they get soggy and float to the top and dissenagrate......what should i do ?

Do puffers eat feeder fish ??
