Nice...I had some like this a few years ago (ok.... quite a few years ago) and was told it was frogspawn by the guy I got it from in Cincinnati. Doing some online research, it seems like there's two lines of thought on it. Either its the same (liveaquaria and animal-world) or its a different species (reefcentral and reef2reef). Looking at pictures, what I always thought was frogspawn is actually called octospawn on the latter. I don't think I've ever seen what they actually show as frogspawn though. Great thing about this wonderful little world of ours :-)
