Firefish

[kuramura]

Hi
Just added a firefish to my tank, looking at the dorsal fin I noticed that bigger fish has single fin and smaller one has it divided into 3 sections, are they M and F ?

BTW Spend some time editing this picture, any major mistakes you guys can point out I would appreciate the comments.

Thank you.

Good job. Looks good to me. The darker background really make the fish stand out.
