chlwong Posted February 10, 2016 Report Share Posted February 10, 2016 I've been scouring around (out of curiosity) for this and I don't have anything that's really concrete.Would someone be able to give me defining features that are different between the two?

DETAquarium Posted February 11, 2016 Report Share Posted February 11, 2016 Are you asking for physical features, or a comparison in water parameters? Quote Link to comment Share on other sites More sharing options...

Mr. F Posted February 11, 2016 Report Share Posted February 11, 2016 As the genus of each suggests, these animals are very similar. One difference between the two is the morphology of the second pleopod (see below). Pleopods are five symmetrical sets of two appendages (aka. swimmerettes) extending from the their first 5 abdominal somites. However, caridina's second pleopod has a ciliated endopod (inner arm) while neocardina's has a clubbed endopod. Another difference is the length of the rostrom ("nose") and peduncle ("chin"), Caridina having the shorter set. Species of each can vary in these parameters and well as size, etc. However, this generally is true for N. davidi (cherries) vs. C. cantonensis (crystals/bees).

chlwong Posted February 12, 2016 Author Report Share Posted February 12, 2016 Are you asking for physical features, or a comparison in water parameters? Both, really. But water parameters would be more useful. Maybe this will help? http://www.thekrib.com/Fish/Shrimp/ That was a pretty interesting read! Thanks!

That was an unexpected amount of detail. I actually came across this website http://www.planetinverts.comwhich i've spent most of my classes browsing. I'm still new to shrimps so anything i find is practically new to me Quote Link to comment Share on other sites More sharing options...
