The spiny eel arrived healthy and seemed active when placed in the tank. It hides well in the sand and is mostly active at night. Easy to maintain in a well-set-up freshwater aquarium.

I noticed it burrows into the substrate at night. It’s quiet and doesn’t disturb other fish. The spines are visible and it looks unique in the tank.

Great addition to my tropical freshwater setup. It’s calm, stays hidden during the day, and only emerges at night. Very satisfied with the purchase.
