AKA the Gold Tetra. They produce what I believe is Guanin, which gives them their gold color. They stay small, school loosely and live a good 2+ years. I have had a group at least that long. They do lose their gold color in time, as they no longer need it as a defense against the specific parasite they exude it for.
Water parameter wise they do fine in the same conditions as most tetras, soft & acidic. Mine seemed to prefer Black water conditions in the beginning, but after a few weeks they did awesome in clear water. Love their Micro pellets.
The pic you show does not show their gold color very well. They are actually silver, but with a healthy amount of Guanin, when they are freshly caught, they are very gold, almost as gold as 10K gold.
Anything else I can tell ya?
