Hay, I just picked up 4 cobalt blue lobsters for $5 each, got them from a guy selling them on kijiji. They are in a 40 gallon. Any info on them would be appreciated. They are babies. What is the best thing to feed them as a staple diet? Right now they are pail because they are stressed but I know each time they shed they get more and more blue but any input about them would be great. Also are they hard to breed? What is the best temperature for them?
