The gorgorian, green brain, plate and tonga mushrooms are all original occupants when I first started getting corals, so about 4 years I guess. The green brain is about 10 inches across when fully expanded, the tongas are huge and spreading everywhere, one is always getting "pushed" off and float around until I nab and stick it someplace. I've always loved the gorgorian, it's not "pretty" like some of the others, but it's just interesting.
Yes, I love my tank!!
