Elephant Ear?

[Apercula]

I just got a nice elephant ear mushroom and was wondering if there is anything special I need to know about keeping them. Other mushroom species in the tank have done very well long term, specifically R. florida and asst actinodiscus colors.
At the moment I suspect the elephant ear may be getting more flow than it really would like based on the flow folding the edges over a bit, but Im not sure if that is just because its still acclimating/not fully expanded yet.

75g mixed reef, mostly softies, polyps, mushrooms, couple lps.
Lights 2x 175w 10k mh
Flow about 2,000gph - return 400gph on a spray bar, 2xkoralia 2, mj900, elephant ear is getting fairly strong flow from one of the koralias.
Ammonia, nitrite, nitrate all 0, ph 8.4,sg 1.025, phosphate 0, ca 420, alk 3meq/l, mag 1200.

Thats a little non specific, they CAN eat small fish.

I was more looking for husbandry tips, Im aware of thier stinging capacity and potential as a predator.

Here it is, its actually more purple than this, I just dont have enough actinic light, and a cheap camera. Its opened about 10inches after 2 days in the tank. The powerhead directly over it is off at the moment, it wasnt liking the flow while acclimating.

I was feeding my anemones yesterday morning and had an extra piece of silverside, so I stuck it across his mouth. The reaction was impressive.
