Flowerhorn juveniles identification

[Flowerhorn neophyte]

Hi, Im trying to determine the sex of my 4 Flowerhorn juveniles. They are all in a 100 gallon tank separated by plexiglass with holes in it. I need to rehome at least 2 or 3 of them, but I'm not sure what I have. Weekly water changes, EHEIM 2217 canister filter. Housed with one Blue eye Pleco.

This is "Big Red" he(?) is supposed to be a Super Red Monkey and is currently being super aggressive and fertilizing eggs. Chameleon

Sorry, didn't mean for the pictures to post twice
This is my "Middle Man" that might be a female (?)

This is my assumed female. She looked pregnant a few weeks back, and I believe she laid the eggs on the statue that "Big Red" fertilized. Eggs are very fuzzy, so possible infertility issues with one of them.

Last one. Any advice would be much appreciated as I am having a hard time deciding who goes to the LFS ?This is "Black Spot" he is not really aggressive and pretty chill. Starting to get terrorized by assumed female. Had to separate them, although they got along quite well previously.That is all for now.
