Happy Little Sorority

My new Sorority tank is going splendidly so far, the five of them are birth sisters for a higher success of homing them together. They co-exist in a 60 liter tank with a LOT of anacharis and duckweed as I'm finding them the easiest to grow so far (please excuse glass grubbiness and water streaks, I've been lazy to wipe it down after water changes )

I have tried to see what tail types they are but I'm failing big time, I don't know how to count the fin rays properly, the fin shapes and and and (so many excuses ) so please help me out with what they are and if possibly explain how to see it

 

I used a site a while back to help with this: https://www.fishlore.com/aquariumfi...ell-the-tailtype-of-your-female-betta.168549/

 

My main tank has 7 females - all co-exist peacefully although I do see a lil hormonal behavior from time to time with my dragon girls. They seem a lil more aggressive compared to their well adjusted sisters. I usually remedy with a lil removal - gradual increases in separation from the main tank so that she doesn't get territorial

 

Thank you @Rust_ee I've looked at that guide as well and still stumped To be honest, I don't really mind what they are, they're cute... when it isn't feeding time that is... then they're little monsters that want all the food for themselves

 

Saw an interesting change in behavior lately... dragon girls have firstly nipped the alpha and her tail was torn but after about 24 hours, has re-merged (torn in half then complete but one can see the seem where it rejoined) - quite quick recovery.
Anyways, Im digressing... they now mimic the alpha and the pack. despite their size methinks they were juveniles.
