Well, ive desided to go along with my plans for a 2.5 pico reef. Im gonna add some corals first, then an invert of my choice. I might not do a mantis this time, but if i find a suitable species for a pico ill do it, but if i dont what would be a good invert? I was thinking something along the lines of a porcelin crab, or a cleaner shrimp.
