Received the eel in good condition, no visible injuries. It has a vibrant base color that seems to deepen after a few weeks. I’ve been feeding it regularly and it’s active in the tank now. The pattern is not as bold as I hoped, but it’s still a healthy and interesting addition.
Sean Turner –
The eel arrived healthy and seems to be adjusting well. Color has changed slightly since arrival, which matches the description of evolving over time. I’m happy with the quality despite the B Grade label.

Great value for a freshwater moray. It’s active and shows signs of improvement in color after a few weeks. No issues with health or behavior. The feeding schedule I followed helped it thrive.
