Cover koralia nano?

[Slystone]

Getting an rbta. Have a small koralia nano 240. Do I need to cover it, or is it too small for rbta to get sucked in to?

In my unfortunate experience, it would be best to cover the Koralia. I lost a BTA to it before I realized I should put something over it. I thought the anemone would be safe with the powerhead since it had been residing in the same spot for weeks. However, one night the anemone decided to "move" and got caught up in the powerhead. There was not saving it. Now I have both a regular BTA and RBTA. The Koralia of Death is still running, but it is wearing a nice pair of panty hose.
