Talk to me about Electric Blue Lobsters...


So, does anyone on here have these? Everything I'm finding on the internet is conflicting info. I've heard they get to be 8 inches big, some sites say 14 inches. My questions are:

How big do they get?
How fast do they grow? Could you start out with a smaller tank (like a 10G) then upgrade a couple of years later or do they grow so fast they need a big tank off the bat?
How long do they live?

And then probably what the next question will be if these suckers require huge tanks are there any dwarf crayfish out there that are blue or vibrantly colored that stay small and can hang in a 10 or 20 gallon?

Ok just in searching I've found the Electric Blue Crayfish may be better suited for a 10g. Anyone have experience with these?

Have had all of these

Electric Blue and also White Alleni crays grow to approx 5 inch, some may get to 6 but in my experience that was top length.

They are extremely aggressive, you only want 1 in a BIG tank (definitely over ten gallons) they will eat your plants, and fish! In fact anything they can put in their claws they eat and as they hunt at night your sleeping fish are a prime target for them.

You'd be better of with Dwarf crays, CPO's which are the small 1 1/2 inch Orange ones.

There is a dwarf species that comes in a blue color (very rare) called Shufeldti...IF you can get a pair of blue ones you can breed the blue color in each generation, but most of the ones on the market are brownish/blue and will NOT breed true.

I raised these last year after buying 3 pairs from a breeder on aquabid, sorry don't remember who it was. All the babies were blue/blue grey and they are very peaceful, can all live happily together in a 10 gallon tank (and did) and I had lots of babies...sold all of them .

Orange CPO's need lots of space, so a tank smaller than 30 gallons is going to create a problem...they get aggressive with one another, especially if one is a female (they usually are bigger too) and they will kill a male or another female over territory.

I just picked a pair up and put them in my 30 gallon and only one of them is still alive

Thank you for the info! Yes, I know the EB Crays are super aggressive, so it would be the only thing in the tank. From what I'm reading floating plants are about the only plant you can go with. I'd like to go with the orange CPOs but this isn't for me, it's for my kiddo so I gotta see what kind of convincing I can do to go smaller.

+1 on the Shufeldti. cajun crays are a common name. less aggressive than cpo and slightlty smaller as well best to get juvies and see their personality develop. there is a pecking order to be established with all crays so be aware. i love em..
