OK I've cought the invert bug after my beloved pinchy RIP.
I now know that there is a fish shop in town that sells them, I heard that they grow to about 5" and I would love to know what minimum tank size and food for them.
Blue lobster is actually a crayfish, and would do fine in a 30 gal tank, keeping in mind it will dig alot, and eat any tankmate that would fit in the 30 with it.
