Determining the sex of a pea puffer (dwarf puffer)

[Madorgn]

I've narrowed it down to the first 4 as girls, and the last 3 as the boy. Does that sound right to you?

And btw, you can just ignore the snail graveyard, lol.

Morning. I've got 5 pea puffers and I'm pretty sure I've got 4 girls and 1 boy. Pics are attached, labeled as I think they are. Ignore the snail graveyard, lol.
