hitchhikers, which was your favourite?

[WheatToast]

My favorite hitchhiker has got to be the Dove snail (Columbellidae). These guys are awesome algae grazers (their small size allows them to reach areas larger snails cannot) and prolific breeders! They aren’t hitchhikers in my tank, though, since I intentionally purchased them from an LFS where they hitchhiked off of live rock:

Egg case:

Not an invertebrate, but Neomeris macroalgae looks wicked in my opinion, though it can become invasive. I sometimes call them “Alien fingers”:

Not an invert, but this dude showed up in my tank a couple of months ago as a baby. It either came in on some cheato or in live rocks.

No idea. Suggestions initially ranged from a cardinal to a killifish to a guppy when I posted a "what is this fish" thread. As it's getting older the coloring seems wrong for a killifish, so I'm wondering if its a guppy or molly. It started out about 1/4" when I first saw it and all green/gold and now it's about 1 1/4". I've called it "Lagniappe."

It's got the wrong bodyshape for a killifish, molly and guppy. maybe a cardinal?

Rainwater killifish (Lucania parva)? These occasionally pop up in refugiums.

Are killifish brackish water then? I’ve always looked at the freshwater side and loved these guys, bet it’d be awesome to have them in a reef.

All joking aside, my absolute favorite has got to be the Acro Crab, Cute little bugger.

Yeah, that's super close to mine. There's just more black on the edges. Pretty little guy!
