Does any one know about these. I cant find anything about them but I just bought one today. it looks alot like a yabbie blue but it is more of a redish brown color. Just wondering what color they are when mature and how big they get.
 
sorry no pics, it is in my 180g now and there is no way (without uprooting everything) to get a good picture and I havent been able to google any up either. It looked to me exactly like the yabbie blues, every marking was identical but the color was more drab and reddish. LFS called it an indonesian lobster and it was in a separate tank next to the yabbies, that is all I know about it.
 
nothing comes to mind, you should google it. I'd also go to images and search for "cherax" or "yabby", and see if an image of your exact cray pops up.

I'll search around a little too. :)
 
I cant find the exact one but it has the markins of this one, spotting, markings on each joint, and linear stripes on the head as the first one. (Cherax quadricarinatus) With the base color of the second one. (Cherax cainii)

Of course the site I found these on is in Dutch so I still have no real info on them still. I am leaning to a orange-brown version of the quadricarinatus at this point but I will keep looking.

I have one like the guy on the left but with more bright RED along the claws. They will change colors dramatically though. As mine has become bigger he has definitely become more dark blue but was more of a drab reddish-brown as a little baby. But still definitely blue not brown... there's a lot of "yabbies" down there in Australia!

They are great pets that supposedly can grow to 12" or more... sorry -40cm or so... I've had mine over a year now and he's about 7", dammit... 25cm!!! (Did I do the conversion right? Trust my dumb American measurements, not my metric guesses)
 
I am actualy doubting the Indonesian lobster claim from the lfs at this point. I have found no evidence that such a thing exists and no one else seems to know anything about them either. I am thinking maybe mine is a brown form of c. quadricarinatus but I am not sure. If you put the brown base color from the bottom cray pic on the quadricarinatus pic that would be exactly what mine looks like. Also I found out that the ridges that mine has on its head are a trait of c. quadricarinatus, I do not know if any other species has this or if they are found anywhere other than Australia yet though.

Oh by the way I am bi-lingual so I speak both inches and cm! Truth be told I talk more in inches feet and yards and pounds than metric, volume I use metric though.
 
Indonesia ain't that far from Australia - could be either or - I've heard of Indonesian Yabbies but never having been there, I can't verify! But the health of the craw is more important than it's origin, right? - and I'm sure with all of the species varieties of Cherax there's bound to be hybrids and mutations galore...

That being said - Yabbies don't act the same as Northern Hemisphere crawfish... from my experiences they are better cleaners, less destructive to the tank and not as successful in killing tankmates. They are slower and North Hemisphere craws pinch harder too! But Yabbies are more territorial than craws. Yabbies don't like other crustaceans. Craws will fight, Yabbies kill. I found out the hard way by losing a beauty of an electric blue craw when I put the two in a 90 gallon tank thinking they had enough space to share.

Also my Yabby doesn't come to the surface or climb out of the tank like so many craws have.
 
Ya, I may not know what exactly it is but it is definitely different than the others I have anyway.

I did have 1 yabbie climb up the filter inlet and dry out on his way across the dining room, my fault though for not sealing the top of the tank off better.

I am putting some in my 180 right now and figured 3-4 would be OK. Do you think that is too many? I have never kept more than 1 in a tank at a time but I need a few good volunteers to clean up after my big messy SA cichlids.
