Free-roaming shrimp
<ul>
<li>Coral-banded - mean a$$ shrimp. Have never stocked one (had planned to before research) based on reputation alone and that every time I look at one in the store, it's tearing something apart that was housed with it.</li>
<li>Blue coral banded - just added, seems like it hides a lot. Very small & likely to stay that way.</li>
<li>Scarlet/"Blood" cleaner shrimp - really attractive, not as prone to stealing food from anemones/LPS, can be pretty reclusive & only seen at mealtimes</li>
<li>Skunk - very active, fears nothing for very long, very prone to stealing food from anything that can't hold onto it.</li>
<li>Peppermint - hides all the time, especially if one or more of the above are present. Be careful to get only ones that hail from the Caribbean (vertical & horizontal "dashed stripes" all along the body) as the Pacific-collected lookalikes (long horizontal stripes) may not be hardy in tropical reef temps. Both are likely enough to go after aiptasia, but if stocking a herd for ongoing control wouldn't you prefer the ones that are likely to live longer?</li>
</ul>
Symbiotic shrimp:
<ul>
<li>Spotted anemone shrimp (periclimenes yucatanicus) - will pick at rock flower anemones & make them go wandering/disappear under rock ledges. Also can be hosted in ricordea patches. Very active.</li>
<li>Venus anemone shrimp - sets up shop in rock flower anemones, will likely steal enough food from it to make it start to shrink unless you step up feeding a lot. Not very active.</li>
<li>"Sexy" shrimp - look really cool, especially if you have several anemones for them to switch between (maxi/mini or rock flower and get 5-7 shrimp. I have too many zoas present to want to risk it, though. But I've watched the little suckers for what feels like hours through the invert tank window, thinking "hmmmmm" often.
</li>
