11 different Caribbean macros arrived yesterday from a fellow reefer from Michigan: Sargassum, Bryothamnion, Galaxaria, Thin Coraline, Gracilaria, Gracilaria Hayi, Fern Caulerpa, Halimedia, Bladed Caulerpa, Sawtooth Caulerpa and Green Grape Caulerpa. I'm going to have to keep an eye on these Caulerpa and get them thinned out when needed, but cool to finally have some color in the tank. Still trying to decide on fish. Thinking about 4 yellow head jawfish for stocking and then something that swims in the water column along with a nice selection of inverts. Have any of you kept arrow crabs in your Caribbean biotopes with fish? I know they can be opportunistic, as other crabs are, but would be curious what kind of a risk I'd be taking with one. I'm really into the crazy inverts available in this hobby. I'd love to add an urchin too, but they'd probably tear up my macroalgae, so I'll stick with macro safe inverts I suppose.
