Who would've thought that animals we used to catch in a dam would one day end up being popular pets?!

These guys are actually fresh water cray fish. In the Eastern states they're called yabbies and over in the west they're called marron. They're exactly the same thing and they're found in waterways right around the whole country.
When we used to catch them as kids they were just a dirty brown colour. But in a fresh water tank, they can be really colourful - have a look at the electric blue marron above.
When you set up a tank it's very important you don't overcrowd them because they will fight. So a tank of this size will contain 2 yabbies of about 10 cm in length and certainly no more and they should be of equal size.
Setting up the tank is pretty much like setting up a fish tank. But don't fill the tank too high or your yabbies will crawl out.
One thing they do need is hidey holes because in nature, they burrow in the side of a bank or dam and that becomes their territory. So provide them with plenty of hidey holes and be sure there's a heap of gravel in the base of the tank too as they do like to dig.

Now the other thing you're going to need is a filter because these guys are very messy eaters and they waste a lot of food, so water can easily become contaminated.
What about feeding? Well in the wild yabbies are omnivores, they eat a mixture of meat and veg, so in a pond they'll eat things like aquatic plants or the carcass of a dead fish - they're great little scavengers. So what do you feed them in a tank?There's a commercial food available which is a complete food and very easy to use.Or, you can make your own. A simple mixture of food like some prawns, peas and carrots. The important thing is to break the food up in small pieces and make sure it's eaten before you give the next piece.
Give the tank a good clean once a month. If you look after these guys they should live for 10 years but be warned, they can grow up to 30 cm long!

The comment made by Jace below is spot on. The Eastern States Yabbie is very different to our local Western Australian marron and smaller gilgie (Aboriginal name). Yabbies are much tougher and have wiped out local species from large areas of habitat. It's actually illegal to have them in an outdoor body of water anywhere west of Albany Highway.
2 Replies"shedding" is actually called moulting and happens when a yabby's exoskeleton grows to big for it, so it "sheds" the old skin and a new one is underneath. moulting is the way that yabbies grow, it happens every so often- its kind of like a yabby's birthday
ReplyI have a yabbie (Sonny) don’t know the sex, which I brought about 2 months ago, he is an active little thing, anyway my tank has ammonia in it which I am treating, I have brought a new tank which is all set up just waiting on my dad to set the filter in it (which he is doing tonight) and he is ready to be put in his new home, now to get down to why I am emailing you, 2 days ago I fed him a bit of carrot which he loves he never touched it, he didn’t even go running over to it like he usually does when I put it in the tank, so yesterday morning before I went to work I put a bit of turtle food in there which again he loves and will go running to it but again he didn’t it fell to the floor and that’s where it was when I left, I left so not sure if he ate it or not but anyway when I got home last night I noticed that he was a bit funny he wasn’t as active as usual and didn’t really look himself (don’t ask me how I know that but I just do), but didn’t think much of it, but I woke up this morning turned his light on and there he was flipped on his back and only moving a little bit (not much at all, his legs were the only thing moving and it was very little movement) I flipped him over and he started slowly moving and went to the top of his barrel and just stayed there I dropped in some more turtle food and it landed on the back of him he didn’t move, he just stayed there, he didn’t even flinch when the food touched him, can you tell me if he is sick and slowly dying or could he be shedding his shell? He has shed his shell before about a month ago but I was away on holidays so I didn’t see what he was like and went through. I came home to the empty shell on the floor of the fish tank :) And if he is shedding then should I leave him in that tank until he dose shed or is it safe to move him into his new tank? Can Anyone help me please!
ReplyI've had my yabbie for 7 months and he/she has shed twice. I know they grow quicker if the water temperature is warmer and food is abundant, but is it normal for them to shed so often? Sometimes, it can eat up to 4 garden worms in no time, especially after shedding, when it seems to have an insatiable appetite. I'd like to get a bigger tank and put a filter in it so that I can get another yabbie, hopefully a "mate", not sure what sex it is??? so that they can breed. Does anyone have any recommendations on what is the best filter to buy that does not cost a fortune??
1 Replyi want to start "breeding" yabbies, but not the big blue ones, more like the tiny white-ish, brown-ish yabbies that you feed TO fish. but i have a problem, i dont know what these litte guys need to stay alive (maybe a pump of some sort) and food is a little different to the big ones. Can anyone help me!! plz!!
