Claire Randall –
The Teira Batfish is absolutely stunning in my 150-gallon tank. It has grown slowly but steadily, and its long fins create a beautiful, flowing presence. I’ve had it for over a year and it’s very peaceful, not bothering other fish. The only thing to note is that it needs a large tank with plenty of live rock for hiding.
Sally Davies –
I was drawn to this fish for its unique look. It’s a bit shy at first, but after a few weeks it started swimming more confidently. I keep it in a large FOWLR setup with stable water parameters. It’s a great addition to a mature marine tank.

The appearance of the Teira Batfish is unlike anything else in my aquarium. Even the juveniles have a striking look with their long fins. After a few months, it settled into its adult form and now dominates the tank with calm grace.
