Blake Slater –
This eel is a striking addition to my 125-gallon tank. It’s aggressive but not overly so, and it stays mostly in its own area. I’ve taken photos and it’s definitely a showpiece. Needs a large tank and careful monitoring of other fish.
Bernadette Mitchell –
The eel is impressive in size and looks very natural. I kept it with a few hardy species, and it didn’t attack them directly. Still, I’ve had to keep it in a separate corner to avoid stress on others.
Oliver Hemmings –
It’s a bold choice. The eel is active and draws attention, but it does chase smaller fish. I’m not sure it’s suitable for a mixed community tank. Works well in a large, well-planted tank with hiding spots.
