Once I finished my stand I decided I didn't want to do any more DIY ever again. But now I have been looking at all these 3D background projects and I might be changing my mind. The problem is I dont want to impede progress to adding fish (I am currently in the middle of cycling). And even if there wasnt water in the tank I dont think im comfortable gluing the modules to the tank. I know some people have proposed magnets - but I was thinking, wouldn't suction cups work just as well? Im still thinking it through but just thought Id throw it out there.
