Horned Blenny and Mimic Filefish

[Stepho725]

Well i ordered these two guys who are due in on Wednesday.

They are both going in my 29 biocube with two occelaris clowns and cleaner shrimp, emerald crab, and CUC.

My problem right now is that my rockwork doesnt have many levels. Its mostly low. As you can see below. Will i need to add more rock/levels for the blenny?

I would at least stack it in the middle. Leave some holes to swim through. How big does that file get?

And yes i plan in moving the rockwork to the middle and leaving some gaps where possible.
