You could rearrange the decor or add a PVC pipe. Or if you're not into the PVC look, you could get some more driftwood and some rocks to create some hiding spots.
not real bad at all. My Gourami seems to like redecorating the entire tank himself anway. I do not think I could find PVC large enough for this dude to fit into. By far the biggest knife I have ever seen LOL.
