I added three Amanos to my planted ten-gallon a week ago, and they mostly seem to hang out in one corner, clustered together. The only other tankmate is a male betta who completely ignores them. One of them molted shortly after I introduced them, but they still don't seem too inclined to explore their new home! At first I figured they were just shy from the new environment, but it's been a week already. Anybody else experience this? I'm stumped!
