My neighbour has one of these in a tank full of fish, and no casualties, unbelievable, but they are awesome, how big do they grow????

sure that is not a crawfish mate?

your other fish don't eat them or try? I am looking for some tank cleaners without getting anymore fish. I purchased some snails yesterday. Can't remember what they are, but they are huge poop eaters...lol

No honestly, I thought that myself, as he has only just started to get into aquariums, but when I popped down to my lfs there was one more in the tank and it is definately a blue lobster. The only time he gets a bit funny is at feeding time, so he actually places his food right outside his little cave, so that the other fish dont go near it!!!

Its about 6 inches!!!

there beautiful but they won,t last much in my tank...big cichlids

The Tigers are pretty mellow. The Australian Blues are the ones to watch out for. I have both.

I don't think the cichlids eat them.. I have three small ones with the Pearlscales....
