Macrobrachium australiense - limbs grow back

Recommended Posts

I have had three of these guys in a tank since April. I thought 2 were female and one was male, because it's literally three times the size of the others. But I read that a dominant male does become oversized, leaving the others small. So now I think that's what happened and I have all males.

I had to separate them because the big one ripped the legs off one of the smaller ones. I didn't notice for a week because he was hiding. He literally had one 'walking' leg left either side and no main claws so he could only hobble along, lurching from side to side.

However, after six weeks' separation and making sure he got food delivered right in front of his nose, this little guy grew back a spindly set of legs that are growing stronger. He hasn't moulted yet, but I am hoping that after he does he will be as good as new. 

I find these guys more interesting than fish or even neocaridina. I think it's those big claws and the way they use them to explore their world as well as brandish them at me when they think I'm holding out on the food. 

Below is recovering victim using new legs and claws.

Wow! I had no idea they could do that, that's so interesting!!! Natives really are fascinating. Good job handling the situation too, sounds like you did exactly the right thing. Poor guy though, hobbling around on 2 legs. Wonder if he looked at you right then and felt as sorry for you (as a two legged human) as you did for him ?

Maybe he did, but he was a sorry sight. Much better now that he's climbing around on all 10 legs.

For the record, Neocaridina and Caridina shrimp that is commonly kept, can also regrow lost limbs.

      Great shot of Big Mama!  I reckon, 1 week tops for hatching.

      Great photo and news. The eggs are fading yellow but there are eyes so all looking good and there are a lot of eggs! Probably about half way ready to hatch.

      Let's hope the big mama can lay safely those eggs

      Sorry, I'm not in that area. 🙃   I prefer Glass tanks. Acrylic scratches way too easily. Often while cleaning algae off the sides. And once it's built up enough scratches, viewing gets obstructed.    Often going with LARGE tanks, you start to fall into custom built stands. So don't be surprised if you cannot find anything suitable.

      The easiest way wouod be to go to an aquarium shop and get a tank with a cabinet made for that tank, as that should be able to support the weight, as water in any large quantity is very heavy. I suspect it would have to be a glass aquarium at that capacity, otherwise the plastic would have to be very thick. It is possible to use a non aquarium specific piece of furniture but as you say it is quite risky, though I did help a friend do that by strengthening a nice decorative piece of furniture they had that they wanted to put a 350L tank on. It has been doing the job for 10 years but also bear in mind water marks, and we had to varnish many coats to make sure water doesn't soak into the wood etc. Its not really worth it in reality, it cost a lot of money to buy all the wood/stuff to strengthen it so was probably no cheaper, and a lot of time doing it. It may be dearer to get a combo tank and stand but much much easier and safer, and only you can know what ones you llike the appearance of? I would start off going to local stores and seeing if they have any you like, and even if not it will give you ideas?
