Reticulate Pipefish (Corythoichthys conspicillatus) キシマイシヨウジ also Network Pipefish
It has a netted pattern with yellow and brown on white on the back. Magenta and white dots on the lower body going back to the dorsal fin. Dorsal fin edged with magenta. Starting at the dorsal fin the network extends further down the body in the mid-section of the fish.
Same Reticulate Pipefish with a wider shot. there is some controversy with this fish. It is said to have been misidentified as Corythoichthys flavofasciatus which is now considered to only be in the Red Sea. I got the Japanese name from my Japanese fish guide which has this fish listed as Corythoichthys flavofasciatus. I am sure the fish has no idea of what we call it.
