Hannah Abraham –
I bought this eel for my 30-gallon tank and it has been thriving. It’s not overly aggressive, and I’ve noticed it’s curious and active. The instructions were clear, and it adapted well to the environment. I’m happy with the choice.
Leonard Underwood –
The eel looks beautiful and fits well in my tank. I had some initial concerns about compatibility, but after reading the guidelines, I placed it with non-susceptible fish. It’s calm now and seems to enjoy the space.
Fiona Nash –
It’s a bit larger than expected, and I had to adjust the tank setup. I’m still learning how to manage its behavior. It’s not aggressive, but I need to keep an eye on it around smaller fish.
