you're aware the "Rubber Eel" is actually a family of Amphibian called the Caecillian?Had a 20" + rubber eel (Typhlonectes natans) get sucked into my FX5 canister filter. The 2 piece intake basket bottom came off and got sucked in a 5 foot tube into the canister. It was pretty gruesome. Eel was all swollen 2 times the normal size from the water flow.
