ID this Crayfish?
 
I was at one of my lps buying a new plant and when I followed the guy to get it bagged up, I saw this cute little Crayfish in a betta container. I pointed out how I thought it was cute (having always liked them) and he went on to explain that it had hitched a ride into the store with their feeder fish shipment. He explained how it was free (with a $5 donation; basically $5). One thing became another and he was practically begging for me to take it (he even knocked off the donation price). I asked a bunch of questions and decided to get it. (I think he knocked the price down because he knew I have a large tank with semi-aggressive and fast fish that I keep at a lower temp)

Anyways, the crayfish is a tanish white color with a bunch of darker flecks over the claws and dorsal regions (black or dark tan spots; basically if you look straight down on him you can see them best). It has a muscular body with (what I think) puny claws (so maybe a female?). The sales person said he had them before and they grew around 3-4 inches. He looks like a non-transparent ghost shrimp on steroids. :P (with specks of course) I also took a good look at him from the side and noticed white blotches that stood out from the light tan. His body shape is that of a Marbled Crayfish but he lacks that coloration (maybe albino?).

I don't have a working camera to take pictures. :<

He gets along with the minnows I have in the tank (just finishing its cycling; tested today with no ammonia) pretty well. I slightly fear for the minnows because they are really tiny (but fast) and seem to like to group around the new guy. :P (seriously, they are millimeters away from his claws)

Also I want to add a group of MTS to the mix of fish. How many should I add? (I also am still thinking about trying Zebra loaches so them with the Crayfish and tiger barbs I have will do a great job in controlling the population)

does the MTS you refer to is Multiple Tank Syndrome????? just kidding a pic would be great there are so many type of crayfish out there.plus you don't know which area it's from.if you did it could narrow the search down.

MTS very much stands for Multiple Tank Syndrome. ;D However, I only have two running tanks up right now (though I have a good number of smaller ones collecting dust). However I'm thinking of buying another 20 gal for the crayfish off craigslist. ;D

I can't take a photo of him without a working camera.... Why did my camera have to go and commit suicide? D':

that crawfish would probably eat loaches, and minnows if it could catch one. I would definately assume it's a 'feeder crawfish', and will devour anything it can catch. (plants, fish, but the MTS might be safe. They can easily be controlled by limiting food though.)

without a pic it is difficult to ID but most crays are NOT fish friendly. They are can and will eat anything they can get their claws on.

Misomie 04-06-2012 03:41 PM

Yeah, I was thinking about him being a possible danger to my fish last night. ^^;

I'll be moving him into the 20 gal when I put my fish in the 75 gal. (then maybe add some surface only fish to the cray's tank)

I'll just set-up a 10 gal as a quarantine tank rather than the 20. ;D

redchigh 04-06-2012 03:44 PM

not sure that would work, even surface fish will sleep on the bottom sometimes.

Even Hatchetfish? I thought they never/rarely left the top... :/

hahahaha except them :lol: i vote new tank for the critter

lol yeah. XD

I'm going to move him in a few more weeks. Since I'm going to be swapping fish from the 20 gal to the 75 gal, which method should I use?

1. Move danios into the 75 gal first and have them stay with the Crayfish for a week or two. Then capture the other fish and place them in bags in the tank while I capture the Crayfish and then swap the tanks completely.

2. Capture Cray and place in bag. Capture all fish and move all at the same time when exchanging.

I have 5 danios, 7 barbs, and 1 CAE. Hmmm....
