Design Flaw with the 14 Gal Biocube

[Louisb]

I am not sure if the other brands have the same issue, but I am having a frequent issue with my onyx clown being able to hop right into the back part of the cube where all of the filtration is. Anyone else having this issue? Did you resolve it and how?

I do have an anemone in there, so I am hoping once they decide to host it then I won't have this problem as often. As of now, it is happening at least 2-3 a week.

Not having this issue with either of my bio cubes, one is the 14.
Is the water too high?

The water level is high, but I only keep it high enough where you don't see the water line under the canopy.
