Paly? ID

[NaClH20NMYVEIN]

Not even sure if these are a paly or not. They get about a big as a quarter. They were plain brown when I got them and I had no where to put them so I super glued them to my HOB overflow and under a lot of light they have really colored up. Got an ID?

Protopalythoa aka Button Polyps or Moon Polyps

There are a few varieties with decent color, but most come in green, browns, and tans. They do grow very fast and will eat small particles of fish food if fed directly.
