This tetra is named テトラオーロ or Tetra Ouro and are 3 cm. This is all I know of them.... Does anyone have any experience with these guys or know any info of them in english?

Also, Im thinking stocking a planted 60cmx30x45 tank with small characin species to accompany a pair of Apistogramma trifasciata and Negro Ottos that I have.

This is the short list so far:

Nannostomus maginatus
Tetra Ouro
Hyphessobrycon amandae
Axelrodia stigmatias

Not sure which combination I'll go for or how many to get but wanna hear your thoughts and experience. Thanks!
