kiwiraka Posted October 14, 2014 Report Share Posted October 14, 2014 Just wondering what causes shrimp to change colour. When i catch shrimp theyre always clear but ive had about six go brown one go gold and one go translucent pink (but he got eaten). Is it from their diet e.g. the pink one might have eaten a lot of heart? Quote Link to comment Share on other sites More sharing options...
Dr A Posted October 14, 2014 Report Share Posted October 14, 2014 The ones I've played around with went more pink with heat. I recall reading the blueish ones were female too. Not that I did very well with them... Quote Link to comment Share on other sites More sharing options...
M@. Posted October 20, 2014 Report Share Posted October 20, 2014 pretty much to do with diet I think Had a couple of bigger females go nearly completely black with gold bits when I had an outbreak of black hair algae - looked awesome! What Dr A said about pink - normally cause they have been slightly cooked by the temp change. If it doesn't kill them they will go back to clear over time Quote Link to comment Share on other sites More sharing options...
Yellow Posted October 21, 2014 Report Share Posted October 21, 2014 I've only seen clear ones, when they mysteriously jumped on me while I was fishing. I'm curious to see photos of these coloured ones. Quote Link to comment Share on other sites More sharing options...

M@. Posted October 21, 2014 Report Share Posted October 21, 2014 took this photo mainly for the eggs, the colouring was darker if you looked more from the top. as you can see, the 'colour' is just deposits in the shell, with the shrimp being mostly clear still. the gold bits were down the 'nose' and at the joins of the tail segments. Got a bit darker than this, but not much. going back to what DR A said about females - In my experience it is normally the bigger ones (therefore probably female) that are more likely to get some pigmentation like this. Being older could mean more time to accumulate pigment between sheds? Quote Link to comment Share on other sites More sharing options...

Being older could mean more time to accumulate pigment between sheds? I would tend to agree with that. One of my females is quite gold/brown Quote Link to comment Share on other sites More sharing options...
