Apistogramma cf. macmasteri (I)
Unidentified Apistogramma sp. that came in as “Wild type agassizii”; they are most certainly not agassizii, and look to be either a locale of A. macmasteri or a related species in the macmasteri complex. Care would be similar to all other Apisto species.

Received these fish as a wild-type specimen and they are very active. The coloration is distinct and they seem to adapt well to the tank. Water parameters were stable and they stayed healthy after a week. Great for a beginner Apistogramma keeper.
Christopher Knox –
They arrived healthy and seem to be a bit more vibrant than typical agassizii. I noticed they establish small territories, which is normal for the species. Tank setup is simple, and they don’t require much maintenance.

The fish are lively and show natural behaviors. I didn’t expect a clear species ID, but they look like a macmasteri variant. They’ve been thriving in a 10-gallon tank with other small tetras.
