Mine are just babies (9-10"?) but if I sneak up on the tank I have caught them in some scary upside down/sideways positions that scare me.. Doesn't happen often thankfully, my footsteps or the fox jumping about hoping for treats usually alerts them before I look, but I've cought them several times lounging in ways that make my hart flutter..
I always fear especially that they share a tank with 3 raph cats and during feedings they often fight they're way into whatever cave or pvc tube the eels are in and I fear injuries with such a spiky body..
Think those cats may move to the "pond" with the cave tetras.
MonsterMinis, how did you know she was full of worms and how exactly did you treat them??
Most of the info I have on worming fish is specific to a problem and/or species specific. I would love to worm my fire eels before I move them!
