Crab recommendation

[Brakaan]

I’m looking for a recommendation for a good crab for my nano tank. It’s a 16 gallon biocube. Current stock:

• 2 Clownfish
• 1 bicolor blenny
• 5 astrea snails
• 2 cerith snails
• 1 nassarius snail
• 1 emerald crab
• Corals: Duncan, Galaxea, Zoanthid, Green Star polyp, Xenia, leather

I have a minor hair algae issue, mostly on the sand bed. No other algae.

what are your favorite crabs and why??

Emerald, because he's a good algae eater.

Is the emerald the only good algae eater?

Probably not.
Yesterday the emerald was eating chaeto, like spaghetti.
Pulling strands with one claw and snipping with the other.
Well, I guess thats not how to eat spaghetti, but it helps the visual.

Scarlet hermits. Only crabs allowed besides small emeralds, and they have completed their job and will be going back to the lfs soon.

Why don’t you like to keep them in the tank after their work is done? I think crabs are fun to watch.

Emeralds cause trouble when they get big. They are fun to watch, just not fun to watch them chomp on corals. Scarlets have always been good to me and are always welcome. Just keep a few shell upgrades and they never bother my nass.
