Girl/boy?

I have 4 angelfish I have recently put into a tank together. I am wondering if anyone could try to guess the gender of them. The koi and platinum are my recent rescues. And I just added my two zebras in with them. The platinum is much smaller than all the rest but is acting crazy trying to nip at everybody else.

 

Angel fish are difficult. The two zebras look male. The platinum and koi look female. It would make sense the platinum being female due to the fighting.

 

No Zebras there. The fin patterns say so. The two look like they may be Silver Gold Marble.

They usually have dark stripes the entire way down their body but they were annoyed that I moved them so the stripes were faded away at the time of the photo. They were listed as zebra angels at the store when I bought them. Although not saying that means it’s correct.

 

Angels are pretty hard to sex until they show their breeding tubes. My best guess is the koi looks like a female, the 2 silver look like Male, the platinum has me stumped. The breeding tube is out in the picture but it's not very clear when I zoom in. It looks thin and narrow like a males but I can't see the end clearly to know if its blunt or pointed. I also can't tell if the stomach is flatter or looks looks egg bearing (bulging) due to the shimmer.

Thank you, this would also make sense due to the fact that I had the two silver ones in my community tank and never got any eggs so they must both be males. The little platinum one is psycho he/she is so teenie tiny yet trying to fight all the other fish since I put the two striped ones in with them.

Also don’t mind how busted up looking the little white one and koi one are. I rescued them a few weeks ago. They were brought to me in a Clorox wipes container that still smelled like lemons

The smallest angel can some times be the most vicious angel. My littlest have always been the fiestiest in my tanks.

 

The best I can give you (educated guesses of course), the gold marble (not a koi) is female, the first silver (has four stripes no more, not a zebra) is male, the second silver is female, the last I say male. Males and females will fight, either in territory or breeding aggression - however females will spawn by themselves and reject males, so they are generally going to be more aggressive during spawning towards other fish (specially if they are going it alone).
As to them not spawning, if they don't like their partner they will not spawn, females sometimes spawn by themselves but there are several experiences of mine where I have had a known female that wouldn't spawn. I also have males and females living together without spawning happening (I also currently have a proven pair that needs to be moved because they are fairly angelfish aggressive).
