Michael Fisher –
The Dot Dash Blenny is a beautiful addition to my 30-gallon tank. It’s active and peaceful, and the coloration is striking. I’ve kept it for over six months with no issues. It enjoys the algae and plants, and it’s easy to care for.
Alison Oliver –
I was impressed by how well it adapted to my tank conditions. The fish is active and stays near the substrate, which is perfect for a small tank. It doesn’t eat much, so I only need to offer a bit of algae wafers.
