Anemone and fan question

[lauren_88]

I have a small powerhead fan in my aquarium. How would I make this safe for a bubble tip anemone? I currently have 2 clowns, a ref fairy wrasse and watchman goby - there is no chance that a fish could swim into the fan is there? Just seems like the front where the blades are is quite open.

Thanks for all your advice

You can buy some sponge to rap around it. I found this article for you!

The "open" part is where it pushes the water out, so I wouldn't be too worried about that area myself. The sides are where the water comes in and the anemone could get pureed. I've personally never found a great solution, although it seems like the circulating pumps like you have don't seem to have as much suction power focused at one point like the traditional powerheads do. On those, I stuff a small piece of foam into the intake to help keep wanderers out.
