I think they're all just sponges. These do come in a wide variety of colors, shapes & sizes.

Will they get outta control u think and are they bad at all

No, I think you'll be ok. While there are some sponges that have been known to smother corals, I don't think these are the ones. Just keep an eye on them though just in case. GL.

Those are my favorite sponges. Typically nutrients in the water will depict their growth rate. If they start to smother a coral they can easily be removed.

I just think they look really cool and add to the diversity to the tank. Some sponge looks drab but that type looks appealing to me.
