Annatasia, I'm pretty sure the first 3 Bettas are in Betta barracks. You can tell because they're in clear boxes with holes and there is water around them
I CANT believe you got a Black Orchid CT from W*M!!! Not to accuse you, that just amazes the heck out of me. The second male looks to be a purple/red Super Delta. I have no idea about the 4th female, she does seem to have a large body but so do a few of my Splenden females. The Betta you're getting from a friend is definitely a girl... she looks to be full of eggs, and you can see her ovipositor (or "eggspot) on the bottom of her belly. Only females have ovipositors, it's a small white dot where eggs come out when they spawn.
