Partially Submerged Posted April 1, 2019 Share Posted April 1, 2019 I am setting up a 60 gallon macroalgae (Caulerpa prolifera and Halymenia dilatata aka "dragon's tongue") and mangrove tank. It has a plateau above the water line, and I'd love to add a small colony of fiddler crabs. Will they eat the algae? Based on my research, fiddler crabs are filter feeders of sorts (they chew through mouthfuls of mud/sand and spit out what's not edible), but obviously they are crabs, soooo... Will my macros be doomed? Quote Link to comment
