I've had a pair of dwarf crays† in my cherry tank
and thus far they menace the shrimp only when
they get within claw range. the crays do not
actively pursue the cherrys, and the shrimp jump
away long before the crays can touch them.
should I be worried now
my crays are still 3cm small,
once they get to full 5cm adult size,
should I then
to be safe, I created a lot of handy places in the tank
for my shrimp to go that are inaccessible to the crays,
however they all share the bottom during feeding time.
