Corals out competing. Or the dinos inside the corals are out competing along with other microfauna is a possibility.
But also, Snowmansnow, are you going by visual look of your tank to determine you have no more dinos?
If I look at my tank right now I would say I have 0 dinos and metronidazole wiped them out. But looking under the microscope tells a different story and that they are still there just that their population has been reduced greatly.
