i have a standard 48" 55 gallon tank. I have a vortech m-p20 on the left side wall, and i place the seaweed on the right side wall. Unfortunately, where i need to put the clip is exactly where my clowns live, RELIGIOUSLY. i think i have seen them swim over to the left side of the tank, maybe 2x in the year and a half that i have had them.
Well, looks like my only option is a stronger clip.
I will see if i can post a video of it. It is actually quite fun to watch.
