Over the span of two months, I've bought a total of 3 Emerald Crabs. The first Emerald crab that went into my 30 is still alive and doing well. My other two Emeralds, one went into my 30 as well and one went into my 15 gallon, bought them in hopes of knocking out some bubble algae. I acclimated all 3 of them the same way, very slowly etc. Lost two of them within a week of adding. Has anyone had issues keeping Emeralds alive? I have multiple Inverts in both tanks doing great.
