I have 2 of these amazing creatures in a 35 gallon tank. Both came together YOUNG but are very territorial. I have a sand base with pieces of drift wood. I enjoy watching them dig the sand from under the drift wood using their large claws to create a cave. They are attracted to glow fish..... A side from that, tiger bars & similar are too fast for them to catch. These blue lobsters are rather ummm.... dumb in my opinion & extremely slow when their claws get to big. I feed mine sinking pellets. A side form that, these guys give me no problems & everyone wants to know how/why you have blue "lobsters". =)
I would be more than happy to trade pictures & advise with you. Mine have been with me for 2 years & have moved homes (I actually moved) 3 times. These guys were my gateway drug into what is now my aquarium store that I call a home.....
Here are my 2 guys as well as my attention junky of a toad fish =P
They're some really hansom looking guys love the colour. Having a slight panic at the moment because I had to remove the cave roof off to get the cucumber out, which freaked him out a fair bit, and he hasn't really seemed to return back to the cave. When I woke up this morning he was at the opposite side of the tank (Usually I wake up and he's still asleep in his cave) so I'm slightly concerned that I've permanently scared him out.
How long did it take yours to get the beautiful colour?
