Anchor Catfish / Hara Hara
Hara sp. is a miniscule species of catfish from South Asia. Barely reaching an inch long, these teeny tiny catfish are a great fish for small setups as they are also quite sedentary. They are incredibly peaceful and will never bother or harm other tankmates; your only concern compatibility-wise is to make sure no potential tankmates are large enough to eat them. These fish are sometimes also known as dwarf anchor cats or moth cats, in reference to the incredibly large (relative to body size) pectoral fins they possess.
These are large adults for this species, almost a full inch long!
| Size | Almost 1 inch (2.5 cm) long |

Added a few Hara catfish to my 5-gallon tank. They’re very calm and don’t disturb other fish. The fins are quite noticeable and add a nice touch. Perfect for a small, peaceful setup.

These little fish are quiet and stay near the bottom. I’ve had them for two months and they’ve grown slightly. No issues with compatibility. A great choice for beginners.

Love how peaceful they are. They don’t swim much and just sit near the substrate. The pectoral fins are unique and stand out in the tank.
