Got these four from a guy on the street. Any body have any clue what they are? Some look like they are getting white edges...

Tank has been set up for a year or more now. Got other inhabitants all doing well. Params are near perfect.

Thanks TangingOut! Thoughts on the white on that favia? All of these are at the bottom to acclimate to lighting...

The white isn't a good sign, but it still has living tissue so under the right coniditions it should make a full recovery. Since it's already at the bottom and getting low light, I would move it out of the shade. Unless you have a shallow tank and really strong lighting.
