Ahh okay, was mainly worried abt the pistol shrimp fighting the banded shrimp. They’re pretty expensive in Australia, I just had a look, $450 AUD for a pairYou shouldn’t have to worry about that as pistol shrimp are aggressive and will hurt anything that gets in the way of its burrow. A shrimp fish will just swim back into its hole and it would be very strange for your banded shrimp to get a hold of it.
