The eel is active and interesting to watch. I’ve kept it in a 75-gallon tank with live rock and it seems to coexist with other fish, though I keep a close eye on it. It’s not aggressive but does show curiosity around the tank edges.
Joshua Johnston –
It’s a unique addition to the tank. I noticed it hides during the day and emerges at night. The size is within the expected range and it appears healthy after a few weeks.
Nicholas Roberts –
The eel is not as active as I expected. I had to adjust the tank setup to provide more hiding spots. It seems to be fine with the reef environment, but I would recommend caution with small invertebrates.
