I just recently bought a GN pleco a couple days ago at about 3" from my lfs. He belly wasnt sunken nor was it fat, more just flat. He is kinda skinny but he doesnt really go for any food i try to give him. Ive tried repashy soilent green, hikari algae wafers, frozen bloodworms, and blanched zucchini. He swims around sometime but mostly hides on various places. How do I get him to eat. Hes currently undergoing treatment with General Cure incase he has worms.
