how many is too many???

i would try the turkey baster to suck them up. a hawkfish should eat them so should a arrow crab(but you may need to take it out when you get more fish there kinda a predator and a hawkfish may not get along with a sixline wrasse)

 

dottybacks eat them, I used to have one for such a problem, but they can get very mean, good thing they stay smaller

 

soon after my tank cycled, I was seeing these constantly. After a few months I started seeing them less and less. Now that you got me thinking about it, I haven't seen one in over a month.

So my experience says they'll thin out as the tank matures...

 

Like lemmings or any wild animal population unless the food supply is there to ensure their numbers the population always drops off people just feed more then the tanks need and breed pest.
