You might want to post this in the Saltwater area. I would make sure your tank is Cycled. Then make sure your water quality is excellent. You may not know, but clownfish are all born female, and the biggest on in the group turns male. So, you might want to buy the 2 biggest, and one will probably already be male. Or the biggest and the smallest, whichever you chose. Make sure there are plenty of places for them to swim and hide. Also, feed them a high quality food. Keep up on the water changes. I would go with atleast 25 percent once a week. You will also need to make sure your ph is high, and that your salt levels in the tank are perfect. Your sooooo lucky, im, a freshwater person, but i've read up on clownfish in hopes to get my own SW tank and have clowns, and maybe a aneome . HOw many pounds of Live Rock did you get?
