need a better picture of the one with the yellow stripe on it's head. Not sure the other is a eureka. Could be a red shoulder, but need a better shot to see where the red is in the body.
want a better shot of the yellow headed one because I do not think it is a peacock, but rather a hap Otopharynx lithobates. You can tell from the elongated lower mouth
All the A.Maylani I have seen, have a darker body coloration .
I'm thinking O.Lithobates or on aVERY long shot maybe even a male N.Venustus. But, it looks too small of a fish for N.Venustus adult colors.
The others look like Eureka to me also. Definatly not Red Shoulders. Maybe one of the Red varities- German, Rubens, Strawberry, ect...
