What's your meanest coral?

[mav3rick478]

I give you my Brown and Teal Goniastrea. One of my first corals frags bought about 1.5 years ago from Petco. It had 2 mouths, was the slowest eater and pretty much did nothing for much of its existence. I moved it from spot to spot trying to find it a happy place then mid last year it finally started to split and form new mouths. It started to eat faster but was still slow compared to my Acans and Palys. I used to keep some Mind Blowing Palys next to it that I got from Ken until it started killing them with it's now 3" sweepers and 10 mouths! Needless to say it now has a perimeter of nothing around it and I will probably have to move those Fruit Loops to the right of it in the near future. Please ignore the Ulva in front, I really should get an Emerald Crab to hopefully eat them up since my tank is to small for a Tang.

Of the corals I've kept, Acanthastrea echinata is the most aggressive. Capable of long sweepers blowing in current and mesentery filaments which can creep upcurrent along the sandbed and annihilate neighbors. Mesentery filaments are so much more lethal than sweepers.

Favias are my #2, with their long long sweepers. I've had a one inch square piece of Favia send out 3" sweepers.

I currently have a Lobophyllia which, while it doesn't have long sweepers, keeps trying to kill a nearby candy cane with its mesentery filaments. It doesn't help that my large Mexican turbo snail keeps bulldozing the Lobo over, sometimes closer to the candy cane.
