Macroalgae's are great in a seahorse aquarium. Colors vary from a unique yellow-orange to reddish color and sure to add pop and color to your display. Some of the coloring of this has to do with lighting it is grow other and individual variation. These are safe to keep with our captive bred seahorses. 


Like our captive bred seahorses, we recommend using RODI water when mixing your saltwater. Corals, macroalgae and other saltwater live animals can be sensitive to improper water quality. We recommend the same water parameters we do for our captive bred seahorses and fish.
