Considering adding a nem to host....advice?

[WienerDog]

I have a 90g (sorta) FOWLR thats about 6 months now (cycled). I do have a few shrooms around for color and I do have a Condy and a maxi mini nem. They have been very healthy and active in my tank. My maxi mini has already split a few times. I think I am ready to add a host nem for my pair of O clowns. I can read on it all day, but what have you guys experienced???
1. What kind of ne?
2. What do I look for?
3. Size???

Is there another tank you could move the condy to?

BTA is probably the best bet. However, I would be concerned about any new anemone clashing with the condy, either physically or chemically. How long have you had the maxi minis? I've never known them to split, but that doesn't mean it's not natural for them. It could be stress, though.
