The seahorse tank is a small modified acrylic critter carrier. It sits below the refugium to collect the mysid shrimp that get washed down through the refugium's overflow.

Water from the refugium enters the seahorse tank through a PVC elbow that directs water along the surface of the tank. It exits the tank through another PVC elbow that serves as an overflow. The opening of the overflow is covered by a powerhead strainer to prevent the seahorses from getting sucked in.

The bottom of the tank is covered with about two inches of sugar-fine silica sand mixed with fine crushed coral. It was inoculated with detritus that was removed from the sump, and now is alive with worms and burrowing crustaceans.

A few pieces of live rock and some macroalgae and seagrass, along with some dried gorgonian branches, provide cover for the mysids and hitching places for the seahorses.

Dwarf seahorses (Hippocampus zosterae) purchased online from The Florida Collector were added on 3/7/02. Some snails, bristle worms and a sea cucumber help keep the tank clean.

The seahorses are fed with live baby brine shrimp. A sponge is used to cover the drain to keep most of the brine shrimp from getting sucked down to the sump.
