Care at a glance
At just a few centimetres, the dwarf seahorse is one of the smallest seahorse species kept in the hobby, which is exactly why it suits a small, dedicated tank. Unlike larger seahorses, it can't hold its own in a regular reef tank: it's a slow eater that loses out to faster tankmates.
Keep it in its own calm tank with low flow, plenty of holdfasts, and only live food such as baby brine shrimp — it won't recognise dry food. Like other seahorses, it does best in a mature, stable tank and in pairs or small groups.
