Yes, looks like A. echinata to me. IME, they are one of the most aggressive corals. Not only can they produce long, like 4", sweepers at night, but they can also extend mesentery filaments that are way more toxic to whatever they touch than sweepers.
Wow, really got it good.Yes! Give it a lot of space. I thought 4" would be enough, I thought wrong.
This Cyphastrea and a Favia were stung by my Enchinata.

Good to know..ThanksYeah that Cyphastrea got spanked repeatedly over a wide area. I'd consider giving the stung part an iodine based dip to disinfect.
Favia can also be aggressive, at least in terms of long sweepers. I had one that couldn't have been 1.5 inches across and yet 4" sweepers would emerge at night.
Personally, I find A. echinata and Faviids very attractive and with proper placement, a beautiful addition to the tank. Oh, and while sweepers generally blow with the current, mesentery filaments can creep along the sand bed upstream!

Just picked up this beauty today. I assume it is an Acan Echinata? If so, I assume from what I have read that I have to be very careful with placement due to its stinging abilities? How much space do I need to give it? I would hate to have to get rid of it since my tank is very full.View attachment 385904
