it''s a green lace shrimp!
they range from many different colors.
I got some from rachel.
This shrimp don't even filter in the current at all.... they love to eat from the bottom and i have not seen any of my three climb my driftwood in the current ever since i got them a month back.
they use their fan to grab food on the bottom or gravel.. i don't think it does anything to them since they are still alive and molting regularly.
