Typical Amano behavior?

[CrashBandit05]

I've had four amano shrimp in my 29gal for about 2-3 months ago. I've noticed they NEVER go on the bottom. Always on or underneath a floating plant. From what I've been reading online, this is not normal but they seem healthy and I've noticed a few molts. I'm not really worried, more curious I guess! 

82-84*F, no ammonia, no nitrites, under 20 nitrates. PH is around 6.5-7.

There could be a couple things, here’s what comes to mind:

1) The temp might be a little toasty for them. I think they can tolerate up until 85 F, but in my experience with my own shrimp and tanks, they seem to be most active at temps around 70-75 F. 

2) If there is anything predatory in the tank like angels or an aggressive betta, they might be beating on them lower in the tank. They might not be killed, but they are getting hassled enough that they are chased up into the floating plants.

@AnimalNerd98 forgot to mention the stocking! 1 German blue ram, 16 candycane tetras, 1 clown pleco, 1 surprise balloon molly fry, 3 black neon tetras, 2 corydoras, 1 nerite snail and various pest snails.

The GBR is the tank boss so maybe the amanos are avoiding him. Not sure if the CC tetras would prey on the amanos too..

Not behavior I’ve experienced.  Sometimes they will hang out up high on the filter tube or wall but for the most part they are down low. 
 

agree that it could be warm or GBR is hunting them.  Or they could just be weird🤷🏼‍♂️
