What can you tell us about the species habitat? Is it legal to remove them and breed them?

This guy was found in a coastal creek flowing directly to the ocean. Typical very soft water, similar to the water parameters in freshwater creeks around Cairns. Neutral pH

I've found the same species locally (Coffs Harbour) as reported in the field trip section, including water parameters.

Its not any more or less difficult to collect and keep than other Australian native shrimp - the same rules apply. I think the freshwater crayfish are the difficult ones - from memory many (all?) Euastacus spp. (aka spiny crayfish) are protected.

Hmm well I'd like to know if you're keeping any? Also i've heard that the blue only occurs in males.. is this true and if so what are the implications for line-breeding colour?

I'm hoping to get my hands on some of these from@northboy in the coming weeks if I'm lucky.. :-)

Not at the moment. I've kept a big male in the past. He was a very interesting inhabitant, quite charasmatic. I've seen full blue and full red/orange females. In fact I'm sure there are some pics of them in the field trip section.

Line breeding - I dont know with these guys because a) I haven't done line bred these and I'm not aware of anyone who has, and b) I suspect the colouration of the males depend on their social status. The macros seem to have a complex hierachy, with the dominant male in an area being the most colourful and the biggest.

      At the time, those babies grown and had babies, those babies also had their babies, during that time, I did not add bacter AE, I never knew what it was, and I was only a beginner, @sdlTBfanUKhelped alot along with @jayc oh, had average 20 babies for each mother shrimp.

      I agree that there probably likely to have more survive with food but if you have 10 already (and there are probably many hiding) that is a good start and it is probably better to get half a dozen each batch (month) than over-run too quickly! You should be fine not using baby food at the moment with the number of babies you have! I had extraordinary survival rates in the original 15L tank which I assume is because they all got some food being such a small tank. Within months of the 8 shrimps breeding I got about 150 babies - it was panic time to get a bigger tank set up! Simon

      I am more of a give a plant a go and it either lives or not, though I don't think anything has died off thus far! I don't know what plants are available to you but they are a personal choice for you to make so just see what there is? I wouldn't use CO2 but if you do decide to use the Flourish excel I would do it slowly starting with half dose etc! I have had algae before with new tanks but it has just cleared up with time on it's own, I guess when the whole system has sorted/balanced itself out! Simon

      Maybe around 10 or so I know that many people claim to have increased baby survival rate by dosing various baby foods or Bacter AE.  What has your survival rate been?

      No plants ‘require’ CO2 so to speak, but it helps boost growth. Flourish excel is basically bottled CO2, so you could do that. Most red plants will just grow a bit greener without CO2. I have some variety of Ludwigia repens, and it stays pretty red, as the leaves reach higher toward the light. But the best thing to do is just try something. Test it out, see what works and what doesn’t, because nobody‘s tanks are the same.
