do you not have fine substrate, or does it just prefer the cave dwelling?somthinsfishy said:I've had the eel for two years. It will eat frozen krill, bloodworms, earthworms, frozen bryne shrimp. It will not eat live fish. It doesn't bury itself thankfully. It's about as fat as a large florescent light bulb. It is very swift at grabbing the earthworms. That's how I got the picture. It will dart out of the cave snatch a worm and return to it's cave in a split second. I got lucky with this picture I made it have to reach for the worm.
