What sex would you say the third one is? I have a fourth that was hiding.

Male, Female, probably Female. The third one looks tiny, so it may be too soon to tell.

Thanks for the opinions.

I added a 5th and some neon tetras and the behavior of the whole tank changed - all 5 are out and about rather than just the 3 in the photographs.

the same thing happened in my tank when i added a school of serpae tetras.
