Fish Going Into Powerheads When Off

So I almost had two fish killed the other day when I was changing from one stationary powerhead to the Hydor branded powerheads. They were in the smallest outflow opening and they were out of water without me knowing for almost 20 minutes. Somehow I found them before they died and got them back into the tank. Now those same fish ( peacock gudgeons ) are somehow in the hydor powerhead which if was on would have blended them up. How can I go about this and keep them out?

Maybe try stretching a section of nylon stocking over the opening? It wouldn't restrict water flow, but should be enough to keep your little explorers away from danger!

Sounds like a decent idea to try. I’d hate to not use the powerheads so I need to figure something out.

Good luck, I hope it works for you!

Sponge filter?

 

Sponge filter?

I have one already up and running just like to have the current sometimes so I can sweep up debris and what not.

 

On a brighter note, I figured they were going in there for a reason and this morning my two females left the powerhead and my male was in there alone.....guarding the eggs.

 

And now a negative note, kuhlI loaches found the eggs and they are all gone. Oh well.
