No not a Sagittae, from what I know, they are more longated like a Devil not tall like a midas. The Red Isletas has more red and look totally different.
I would guess it is just a barred Midas. But you have a few others that look like a barred Midas also. The Amarillo, Hogaboomarum, Chancho. The Hoga and Chancho are more of a yellowish color. If I had to guess I would say a barred Midas, or Amarillo. But Amarillo's are not easy to find.
If you can get more info as to where you got it.
Just noticed, are the fish in the dull looking pictures the same as the one in the clear picture?
The clear pic looks like a nice looking red devil, and possibly a sagittae.
