Yep.The one that I had was quite active and always exploring the tank.I even had a skull ornament for it to hide in and it would go in and out of it as it made it's way around.Feeding it is a whole different matter though lol.Fire Eel!
After i discovered my fire eel loves worms he is out swimming most anytime he sees me.
He used to bury in the rocks, but since i added that ugly pvc tube (24 inch tube) he loves being in the tube. Now no more digging.
He is currently in a 90 gallon grow out/quarantine tank.
He is fast becoming my favorite fish. I got him this size.
