Acan Identification

[Daryl.h]

I got these from someone a few weeks ago and really don't know what type of Acans they are or what can or cannot go next to each other. Any input is appreciated!

So I could be wrong but they almost all look like acan lords to me and while they do have sweeper/stinging tentacles they are very very short so most things can go next to them with no problem.
