I done some moving around today soI pulled these 4 to check them out. What do you guys think? all fish are oer 2.5". I know fish 3 looks stressed. He gets like that every time its removed but darkens up as soon as I put it back in the tank.
I say:
1. male
2. female (no otonodes or hairy fins)
3. male
4. male
Fish 1

Fish 2

Fish 3


Fish 4

hi

hm not easy to say, i think you might be right.. number 3 looks very stressed, a bit as he returned from a boxing fight...

I think 1, 3, 4 are male;
2 looks like a male to me, too...

they all look like boys to me... but I've been wrong before ....
