LPS coral id help.

I got this coral for free from the place im currently semi working at, can anyone tell me what lps it is? There are a few ive looked up online but i cant really pinpoint which one exactly.

It may be Acanthastrea echinata, or some sort of chalice. The leftmost polyp looks more like echinata though.

Hard to tell from the picture. I agree that either a chalice or an echinata. Both can be aggressive Coral and both like lower flow. Echinata like low light. Some chalices prefer med light but do okay in low light.

Looks like Echonophyllia cf aspera
