It's a 55 gallon breeder tank where I built-in the sump and refugium as a peninsula to the left. Build photos are in my profile. Don't have the room for the peninsula, but planning to sell it eventually anyway. I know the rock work is a little busy, but the colors are finally starting to blend in well. Honest opinions on how this can be improved, even if it's to remove something. Maybe some low light corals in the shaded areas? What animal can I put in the refugium as a display that won't eat the copepods? Are there different macroalgea than cheato?

Snail ID?

LFS said it was an Aussie Rock Snail. Looks encrusted or like someone glued a frag on it. Moves slow, clumsy as hell, and has tube worms growing on it. Possibly more, but nothing soft. The large tube at the underside had a large bristle worm in it that eventually moved to the rockwork. Keeping them under control with a wrass for now, but can't find any info on this snail. Not sure if the bristle worm was symbiotic or just a hitchhiker.
