picture of things under my rocks ..and sun corals??

[NewFishy]

I've always wondered what this is after bringing this live rock home..




This pink stuff use to have a long arm growing from it..it recently had broken off...










In thos to pictures I just wonder...are they corals or any kind? I only have normal lighting in my tank ...are they dead corals?







And lastly do you have any tips and keeping these alive?????

Those first few pics are definitely sponges, but that last pic is a mystery.

Looks like it could be sun coral

Normal lighting

I agree, look like Sun Coral polyps (Tubastrea), which would be under a rock or overhang, because they are non-photosynthetic. I feed mine a mix of cyclopeeze, h2o life coral food mix, live phyto, super shrimp every other day. I change up the blend every feeding ( targeted). Larger heads will eat Mysids too. Likes low light, and moderate flow.

it's not a sun coral. Those are Balanophyllia.

Good or bad??

They are good, but also need target feeding and don't utilize light.

This is a sun coral. Shot at night inside the wreck of the Rhone.
