Thank you very much for your answers gentlemen, okay i'll stick to the basic then, my plan for now is to change one of the mesh in the top to glass, and i'll use some cork walls to do some rocks with foam, and one hidding place for him, then i'll put some dry substrat with silicone, and i'll put some plants in another side, glued to the wall too this should look good i hope, thanks again guys will show you my work later
