I’m getting an electric eel soon and I’m pretty sure I’m ready for one except for one thing. The seller I’m buying it from keeps it in a large plastic tub. Sort of like a big clear storage bin. He told me that when he keeps them with filtration, they lose their slime coats, get infections, and die. I don’t want to keep mine in a tub, I want to keep mine in a large tank where I can actually view it. Anyone know anything about this?
