foraminiferan

[Emma Gilbride]

Could some one identify the foraminiferan pictured on page 172, lower left, of "The Modern Coral Reef Aquarium", vol. 1. I have lots of it growing in my tank, some specimens are 1.5cm long and very bushy. Most of the underside of one large piece of branching live rock is covered with it! Regrettably, due to the position of the specimens I can't get a decent photo of them, hence the reference to MCRAv1.

Thanks,
Emma
