I shall use that picture as reference, thanks a bunch! I just got a female crowntail falsely being advertised as a female veiltail. Shes larger than the other females, but smaller than my oldest.
I also removed one of my females from the tank, even though she was in her cup. I beleive she has the early stages of Fin-Rot.
I removed my halfmoon male into a cup and used his holding-tank as a hospital tank. It's a half-gallon tank.
The female has white spots on her dorsal, anal and lower back fins. Her anal fin also has a few tiny tiny holes, is a bit black at the tip, and has a missing peice. The missing peice was not in her cup.
Image of her in the holding tank. The delta tail male is also in a holding tank
