Amano Shrimp

[Kagh't]

amanos are naturally from japanese mountain streams which are in the region of 18-22c, but can survive higher temperatures.
HOWEVER, like any other cold blooded animal, the higher temps increase metabolitic rates, decreasing the life span, and putting undue stress on the shrimp.
yes, they may live in higher temps, but they certainly won't appreciate it.

I've always read that they are from marsh/swamp areas.

To quote Joe Anderson*:

"The Yamato Numa Ebi, which can be translated as Japanese Marsh or Grass Shrimp, is taxonomically identified as Caridina japonica."

That would imply that they are not mountain natives, plus there seems to be improved breeding/rearing success with at least slightly brackish water- which is consistent with estuarine marshes.

I suspect that the issue is that these are temperate creatures, not tropical, so that higher tenperatures year-round are not natural to them and are likely to shorten their lifespan.

Mine were fine with ich treatment, but I was really careful & did regular water changes. They do craw out of the tank if they get the chance. many other shrimp species will too! Found this out the hard way with a heavily planted tank. I guess they got up on a plant and then crawled out thru a small slit in the tank hood....
