Jason Allan –
Added the Pebble Crab to my 100-gallon reef tank last month. It’s been active and doesn’t seem to disturb the corals. The water remains stable and the tank feels more natural. Great addition for a balanced ecosystem.
Nicholas Anderson –
The crab arrived quickly and looks exactly as described. It’s been living in my tank for three weeks and seems healthy. I didn’t see any signs of aggression or damage to other inhabitants.
Jasmine Carr –
I was skeptical at first, but after a few weeks, I can see the difference in the tank’s activity. The crab moves around naturally and helps with cleaning small debris. Very satisfied with the purchase.
