Ruby Tetra (Axelrodia riesei)
Axelrodia riesei is a diminutive tetra from Colombia. These tiny schoolers don’t even reach an inch in length and are thus among the smallest of all tetras. Their reddish-orange colouration is accentuated with blackwater conditions and high-quality foods. They pair well with other true nano fishes, and also make good dithers for small dwarf cichlids.
These are wild-caught adults around X inches long, highly prized for intense red colouration that simply cannot be achieved with captive bred specimens.

The Ruby Tetras arrived healthy and vibrant. Their red color really stands out in the tank. I’ve kept them with dwarf cichlids and they get along well. Easy to maintain and very active in a small community setup.

These fish are small but lively. The red coloration is impressive, especially after a few weeks in blackwater setup. I noticed a difference in their appearance compared to captive-bred ones. Slightly more active than expected.

Great addition to a nano tank. They school well and don’t stress other fish. The color is intense and natural. I’ve kept them for over three months and they remain healthy and active.
