Hi guys, never had Amano shrimp before but recently got a group of 5 from the lfs. Very carefully acclimated them and they have all been fine for the past week and a bit. The only thing is they all seem to hang about together on the spray bar (which is just under the water) all day. Haven't seen any sign of them trying to actually escape or get out of the water, but they generally don't seem to move far from that area. The tank is heavily planted and has lots of hiding spots, so I am not sure what else I can do to encourage them to explore. My water parameters are always pretty stable (and fairly comparable to the lfs water) and I do a 50% change weekly. Has anyone else experienced this with Amanos?
