We’ve Been Hunting a ‘Tonga-Mussa’ for Over Five Years!

Wild 4-Way Homophyllia coral is four times the Scoly

What you are seeing here is a very peculiar coral, both in color, pattern, and especially the fact that there are four corallites growing closely into a mini colony. This head-scratching and head-turning coral was collected in Australia by Ultra…

Couple of Great Homophyllia australis at World Wide Corals

Homophyllia might have taken over as the name for Scolymia but that doesn’t mean we’ve lost any love for the ‘Australis’ doughnut coral. Hundreds of these corals are exported from Australia every week, and by and large, every single one of…
