Just got these Acarichthys heckelii. Pushing a good 5 inches. Settled in super well. Pretty pumped about these fish. Just need to add a few more geophagus altifrons or may get rapps wild sveni and the tank will be complete.
They are pukka fish, here's a photo of mine but he's a bit stressed, colour not really showing. Soon as I walk to the tank with my phone he turns on me he don't like having his photo taken but ther are really good fish
