I have in the past put in 20 pcs(for 4 feet tank), you might not end up with 20 because some of them might crawl out. They have a tendency to crawl out when it's adjusting from another tank.
Try not to go above 20 because they are very destructive, and especially when u have smaller shrimps or fishes. I would reckon that if you can, try with 10 pcs first and if not enough, slowly add.
