Please help sexing L025

[teng]

Hi, I'm about to get a group of L25 and not sure about their sex; it would be great if anyone can help me out. They are all about 10-12 inches and wild caught.

THANKS SO MUCH

I'm going to house them in 39x30 inches tank. Is it okay for 4 of them?

Fish 1 and 3 look like males to me, Fish 4 female and fish 2 my guess would also be female.

The tank is too small. These fish can be very aggressive towards each other.

Thanks for your opinion Frank.
I'll housed them in 72x24x24 inches tank instead; or if they are really 2 pair then maybe 39x30 tank for each pair.
