I have looked again at your fish, and wish to change my assessment -
I am not sure which of the two fish you were referring to, as "looking weird'. You did mention that you felt the red splotches didn't look like others you have seen.
The specimen with the long, red (black edged) hook in the anal fin, and the red splotches on the body, is not a female
M. schomburgkii after all, but a female
Myleus rubripinnis, aka, red hook silver dollar. I felt earlier it was a female
M. schomburgkii, in error.
The male is a typical male
M. schomburgkii, although that name is applied to what may be 2-3 (or more?) different taxa or varieties (wide bar, thin bar, blue hook).
Small red splotches on the sides of
M. schomburgkii do occur, but are not that frequent. Large areas of red on the body (not as spots) are common when they are displaying. On the other hand, red spotting on
M. rubripinnis is fairly standard for adult fish.
All together, and despite my previous statement, I believe you have a male and female of 2 different silver dollars. Again, very nice adult fish.
I believe
