I'm thinking about getting an emerald crab to help with some gha I have in my tank, I've read people have had them eat corals etc but is this because they run out of food in the aquarium? Or will they still pose a risk to corals with GHA present?

Get female Emerald crab.Male is known to pick on corals and are more aggressive, females are less aggressive and less likely to pick at your corals , if you really want an emerald crab.
Telling the difference between a male and female crab is straightforward. If you turn the crab upside down and look at the abdomen flaps, the female flap is larger and rounder than the male flap, which is smaller / narrower with a more pointed end.

I just got an emerald crab for my tank and he's a MONSTER at eating algae I love him already. I've always liked them and I've had a few over the years. For me they never live very long though... [emoji53]
