Those aren’t neos those are cardinia. Very beautiful though I wish I had better luck keeping cardina but my water doesn’t agree with there liking.
Yes. Sorry you are right. They are Caridina cantonensis.
I was watching a Youtube video by L.R. Bretz on neocardinia shrimp at the time I was typing.
GH is important for their long term success. Keep a tight watch on KH and GH. Treat yo water right and it will treat yo shrimp right.
Here are some more pics. He has a very interesting color variation that is black with orange eyes.
And a few shots of his setup
PVC air line runs throughout the fish room from a single pump.
Water aging tanks are on top of racks. He drains the tank water and it is auto topped off with the the small ball valves by gravity after opening a drain valve on the aging tanks.
All water incoming is run through an RO unit, the GH and KH tested-adjusted-retested, sent to the top tanks and aged for a day or two.
He uses almost exclusively sponge filters. Most tanks are 20gal (45cm X 60cm footprint)
20+ tanks of his roughly 140 shrimp tanks
