Aphyocharax anisitsi

• Lived in the AA fishroom before.

A temperate fish, best kept at room temperature. Very active.

Boehlkea fredcochui 

• Currently in the AA fishroom (update 20 May 2024).

A beautiful fish if light reflects on it. Seems drap and gray but harbours a wonderful light blue. Supposedly spawn under broad-leaved plants, but remains to be seen.

Carnegiella strigata 

• Currently in the AA fishroom (update 20 May 2024).

Accessible and small 'oddball'. Feeds off the surface, so feed floating foods. Should be breedable in soft water. They jump and almost fly, to keep the lid closed or keep the water level at least ten cm below the rim.

Gymnocorymbus ternetzi

• Currently in the AA fishroom (update 20 May 2024).

Black-and-white tetra from the temperate waters of southern South America.

Hyphessobrycon amandae

• Currently in the AA fishroom (update 20 May 2024).

Pretty little tetra. Very small, maybe 2,5cm fully grown. Breedable in softwater, but fry will be the tiniest.

Hyphessobrycon herbertaxelrodi

• Currently in the AA fishroom (update 20 May 2024).

This is a goodlooking fish if you're into black-and-white. Named after the infamous fish publisher and tax evader Herbert Axelrod. 

Moenkhausia sanctaefilomenae

Nannostomus cf. digrammus

• Lived in the AA fishroom before.

A small pencilfish. In my tank they school with Hyphessobrycon herbertaxelrodi. I wonder if they think they are the same. Their pattern (see name) changes at night, when it is suddenly dotted. Bought as N. trifasciatus, but they do not have any red on them, so now tentatively relabeled at N. digrammus. Could also be N. marylinae. Let us know if you can identify them.

Paracheirodon axelrodi

• Currently in the AA fishroom (update 20 May 2024).

Perhaps the most famous and certainly the prettiest of tetras. Always abundantly available. No Amazonian community tank is complete without. Prefers soft, stained water.

Nematobrycon palmeri

• Currently in the AA fishroom (update 20 May 2024).

One of the larger small tetra's. Has a pink hue over its grey-black flanks and fanciful fins. Quite an attractive fish.

Phenacogrammus interruptus

• Currently in the AA fishroom (update 20 May 2024).

An African tetra from the Congo river bassin. Breeding them is a science, but these are very shiny fish when they are in the mood. Grow larger than your average tetra.
