It could work, because spiny Eels are very flexible, but for comfort of the fish, 24"+ is usually the bare minimum, doing a 3 point turn just to move around your own house is not comfy!Anyone have input on keeping a fire eel is a large, but skinny, aquarium?
I'm planning a basement remodel and want to build a room divider peninsula aquarium. It'll be plenty long (8' or 10') and plenty tall (3' is my current thought), but there isn't much room for width. Honestly 18" is pushing it for the layout I'm thinking.
Tank mates would be smaller and more active fish; clown loaches, silver dollars, discus, etc.
