Nem Species Tank

[Titch]

Hi I’m new to the board but not too reefing. After 5 years of keeping a reef aquarium I thought about making a species tank for an anemone. I have already kept a Heteractis Crispa in the past for 3 years before selling it.
I have been looking into making this tank for a while now but after doing some research I’ve found that stated sizes anemones seems to vary from site too site. I already have a Aquarium that’s 36 inches long 18 wide and 20 high. I would like too know please, what species will be ok size wise in this tank?


I have always wanted a Heteractis Magnifica but I fear that my existing tank will be too small for it from what I’ve read? If someone could confirm this it would be very helpful. I just want to see what my options are using what I have already and if it doesn’t suit something I like ill purchase something new.

Any help weighing up the options would be very helpful ty
