Hey @TangGang thanks for stopping by! Tbh I'm not really sure what species this particular shroom is! Probably have to call in @hcker99 with Ultimate Corals for exact ID on that. Me and @MERKEY snagged a cpl of these guys up awhile back in a flash sale and haven't seen anything like it come back around. Def a unique shroom. Super bouncy and doing real good. Hoping it starts dropping babies soon!Is this a blue St. Thomas? It’s awesome haha just like the rest of this lagoon
