Help pick an invert for 15g

[tonym10]

Help me pick a good interesting to see invert for my 15g cube. Current inhabitants are :
1 Clown
1 Bicolor blennie
1 yasha gobie
1 emerald crab
1 Pistol shrimp for the gobie, but they ahvnt paired and I never see the shrimp.
Lots of snails.
Corals, acans, blastos, ricordia, xenia.
I would like an invert thats safe with what I have and wont hide, and is fun to look at and watch, a shrimp, starfish, etc... any ideas?

cleaner shrimp, mine goes nuts when fed and never hides, peppermints are cool too but mine hid till i got hte cleaner. Sexy shrimp are also really cool, although the pistol might kill it.

Pompom crabs are great although many will hide. Mine is out and about anytime it thinks food is nearby.

I have a cleaner shrimp in my 15 gal and he is all over the place, nonstop movement, I would highly recommend a cleaner shrimp and safe and nonaggressive towards other inhabitants in the tank.

Thanks for the replies, I forgot I do have a pompom crab that I never see too. I thouhgt about a cleaner shrimp , but was concerned about one crawing all over the corals in such a small tank and causing the corals to retract.

Get around 10-15 Cerith Snails. I have 10 in my 20 and they are already going a good job of cleaning the liverock.

I am not looking for a clean up crew. Just something fun to see.

A porcelain anemone crab is a great invert. Reef safe and they'll host any wavy organism you have. You mentioned xenia...mine hosted pulsing xenia until I got him a BTA.

Definitely the cleaner shrimp and/or blood/fire shrimp, both very gregarious.
