Is there a feed you can suggest?Technically, your fish is not the 'holotype form' of A. eunotus. It is a closely related population/form/species. The true A. eunotus has not been in the hobby for more the 30 years. Nevertheless, your fish behaves, breeds, and needs the same requirements as most other forms presently sold under the name "A. eunotus". See http://www.seriouslyfish.com/species/apistogramma-eunotus/ for a good overview.
