Here is my Tubastrea when I first got it in March "07. With my Blue Spot jawfish Dotty.
Here is a close up.
Here it is on the rockwork.
Here is is when I first moved it to the sandbed around August "07.
Here it is today. I feed it mysis and cyclopseze.
Here is my black Tubastrea. A stunning specimen, but more difficult than the yellow IMO. I've had it for about 3 months. It opens regularly.
