Pretty fish. Reminds me of a white cloud minnow (is it a white claim I'd under a different name?)... Been a while since I've seen a white cloud though so idk.
Could we see pics of them in your tank if you dont mind?
For ages, since the 1920s, we thought the white cloud, Tanichthys albonubes, was the lone member of its group. The in 2001, T. micagemmae and T. thacbaensis were described. 2019 brought us T. kuehnei, and this year, 2022, featured the description of 2 more group members, T. albiventris and T. flavianalis. The cardinal minnow (such terrible marketing names) is Tanichthys micagemmae.
