Tatia gyrina's caudal fin

[tatiaman]

The other day, I bought a mysterious tatia. This tatia has a very long caudal fin! I'm guessing it's gyrina from its color and provenance. This characteristic was seen in several individuals that came in together, and I thought it was probably a male with an extended
caudalfin. But, I don't know gyrina has such a characteristic.

I've never seen that before. Very pretty!

The most recent work on Tatia as a group mentions elongate caudal fin on "some males" but it's not characteristic for any species. T. gyrina is widespread, so it could be a population that has this feature, could be something new, could not even be a Tatia if we looked closely enough.

Does it not look a little elongate?

Glanidium

?

I have seen tatia strigata has elongate caudal fin, but it didn't exist as a population. From the point of view, this tatia is very interesting.

Sorry, I can't understand difference between tatia and glanidium except cover on eyes andan anal fin…

I sent another picture of this tatia.
