SPS Bleaching

[Aquattro]

To find the acro flatworms, take a coral out and place it in a white bowl. Use a turkey baster to blast around the base and see if anything comes off. The flatworms are about 5mm long and have a speckled brown coloration!
Freshwater dips kill them, but once they're in the tank, you may need to use a sixline wrasse and train it to eat them. You can do that by dislodging them from the corals with a baster again so that the wrasse sees them. Then it should go looking for them on it's own.
