The yellow seahorse is, as its name suggests, usually yellow, but its coloring
gets darker in poor environmental conditions. It stays in a vertical position, with
its tail serving to cling on to the decor (which must be free of Coelenterates).
In captivity, it feeds on brine shrimps or other small, live prey. Reproduction
may be possible in captivity: the male incubates the eggs in its ventral pocket.
Size: 15 cm.
