Hello, My tire track eel has recently been sticking his nose out of the water, and pushing his body a good 4 inches out of the water trying to get into my filter. right where the water comes out of the filter and into the tank, he's managed to push off my filter lid. I know any elongated fish is usually notorious for jumping. on my old lighting system i had a screen, cut from an old screen door, that was taped across the top to keep my AF. butterfly fish from jumping out, but for the eel, he is a lil more nifty and could easily find gap between the screen pieces and shove himself out. I was wondering if there was a way to cover the area without impeding filter flow. thanks.
