I've got a cycled, 3-month-old Fluval spec 2 with 3 or 4 snails (bladder and trumpet) and one rili shrimp (LFS had only one).
My question is this. I'm planning to ad 10 or so more rili shrimps, but I'm wondering if I add them all at once, will it overload the biofilter from the difference in bioload? I'm probably have to order them online, so I'll have to add them at once.

10 should be fine.

Should, but I would have some changing water prepared and check the ammonia
for a couple of days after you put them in there.
People have had dozens in ten g tanks but the pop grew in there and the bacteria did
as it happened.
