My Tank Thread
My Aquarium Showcase
Same here, had plenty of emerald Crabs to start, some died,,some got too big for tank, eventually had 0 Emerald Crabs, fast Forward to about 1.5 months ago, found a few bubble algae, got 5 Emerald Crabs, no more Bubble algae...and they have never bothered coral in my 40B.Emerald crab took care of my bubble algea problems. Every once in a while I'll see a bubble somewhere remote in the tank and think, "this guy will never find it". To my surprise he ashtrays dies.
