Do Amano shrimp have a minimum group size?

[LancsRick]

Pretty sure the hair algae I've been plagued with is actually filamentous diatoms (appears there is a strong link with new Fluval stratum substrate and this). As a result, I was going to employ the ever faithful Amano shrimp. Given it's only a 30l tank, I reckon the most I can reasonably put in would be 3, but given I want to add Red Cherries later, I was going to just put 1 in (hopefully it will also avoid eating my plants as there will be enough food for it!). Any issues with putting in a single amano?

Why not just add the cherries they eat algae too

I didn't think they ate filamentous diatoms though?

Will you be able to rehouse the amano at a later date ime they can out compete other dwarf shrimp for food.

I had 3 amanos and 2 died so I have one living alone. It seems healthy although I cannot comment on its emotional state

Rehousing them won't be a problem Tim.

From careful observation I reckon the emotional state of amano shrimp is perpetually "cheeky"!
