I have a hang-on back filter with a very low output system that hangs into the tank and my fire eel keeps swimming upstream into the filter. It keeps getting cuts and scrapes from the filter media and I keep having to get him out with a net. I'm currently treating the tank with an antiseptic and anti-bacterial treatment and the eel should be ok but I'm not sure how to prevent my eel from swimming up the output of my filter. Does anyone have any suggestions on how to fix this problem?
