Look at this guy doing as he pleases

i've had 6 emeralds over the years and none of them have been anything but model citizens, if they can catch a shrimp or fish, they were sick and dying anyway, emeralds are not fast enough to catch anything faster than a snail.

corals aren't very fast. . .

Then how do other carnivorous crabs survive? Btw. You like to throw facts around. I sure hope some Noob doesn't buy this. I'd like to see a single source. You may have had gl or they are dieing before they turn rogue. Its not a blanket statement saying all emeralds are bad. It really depends on specimen. Surely if they pick all ha and bubble algae its gonna need food. Emeralds have no place in a clean tank. They will only become predatory to survive.
 
I had one kill a Flame Angel and Clown everytime a fish would swoop by he would extend his claws and take a swing hoping to get one, I didn't catch them doing it but munching after words fish got along fine so there was no aggression.
 
why do i have to cite an example, how about you cite a scientific source claiming they actually eat the coral tissue and are not just trying to steal food from the polyps? Believe what you like, i dont really care, I hope a noob doesn't read your false information and believe they are bad right out. i suppose if you starve them they may try to eat coral, but in my experience i have never starved any of my livestock, not saying they haven't ripped up a euphilla here or there trying to get a meaty morsel.
 
I think there is enough personal evidence. I don't need cite anything. I'd add an emerald, but keep cautious. If you want to throw out blanket statements then a cite is need. I'm pretty sure there is a majority here. WITH CAUTION. If you have a few pieces of bubble algae then manual removal is best. An emerald will eventually outgrow small reefs and terrorize corals. If not eating them these clumsy guys are capable of moving rocks and ungluing frags. I've seen this first hand. If you have a large reef, then a tang is best.

First thing is good husbandry. Low nutrients won't allow pest algae to take off. Avoiding the emerald crab discussion all together.

Nothing personal diver. A Noob will likely add a few because they are so cheap and regret it down the road.
