Wood advice

Hi,

I have a lovely large piece of wood that I've soaked and is ready to put in my tank. My only concern, is that I feel there's lots of places for fish to get stuck. Am I over thinking it or does anyone have a recommendation how to fill these gaps? I have some relatively big fish which worry me, but my clown loaches are still on the smaller side.

I've had small clown loaches get stuck in bogwood before, thankfully they survived, but would rather avoid it happening again if possible.

Any advice is welcome, or of course feel free to tell me I'm over thinking this.
