How many powerheads for Ritteri?

[AliKat]

I want to try keeping a Ritteri. I know all of the risks and that it's difficult, but still want to give it a try.

I have a 55 tall, which is 36 inches in length. How many powerheads would I need to hook up to a wavemaker? Would they all need to be pointed at the Ritteri?

Thanks for your help!

I'm also looking for a good place to buy one online if anyone knows of anywhere. Obviously it makes me a little nervous to buy something like this sight unseen, so please let me know if you've bought a pretty and healthy Ritteri from someone online and had a good experience.

You will want enough water flow so that the tank volume turns over I'd say 20 times per hour. So say you have ~40 gallons of water (sans the rocks, etc.), then a combined flow rate of at least 800 gallons per hour. And as far as pointing directly at the anemone, I would point the water just above the tentacles so it gets good flow, but not pointed right on it.
