Thats what I was thinking, except bred with the flourescent green gene. Personally I think these look better then the danio version!
As said before, probably wouldnt put any in my tank, but those are super cool looking!
Actually they look like zombies... Not for my tank personally...
Unless you did an all zombie themed tank.. You could create a little cemetery at the bottom.. get some evil dead and return of the evil dead merchandise and plant it strategically around the tank.
You would have to have regular white skirt tetras as the main inhabitants and then get 5-7 of these as the zombified versions... could be fun for little while.
