I have a blue lobster and have had him for several months, nut I am not sure what size tank he needs. I cureently have him in a 3 gallon mini-tank, with a filter, etc.

I guess no one knows much about blue lobsters?

Well, I can't help u much, but I was able to find you this website for information
the page

That website was pretty helpful. I also found a website that sells them and has some other useful information in the event anyone is interested:
