Pictus catfish fighting

[rockyofhockey]

I recently purchased two pitcus catfish for my 46 gallon bow front. Now they r constantly fighting for this rock cave right under the filter when we have like 20 different rock caves. Is this normal or should I be concerned?

Reorganize the rock structures all of them
