As they mature, they undergo a transition, shifting from erratic monochromes to a more minimalistic horizontal white stripe against their charcoal bodies. Their facial patterns develop into just a spatter of bright white dots. The Kamohara Blenny is reported to reach a size of 6cm but we have found that our broodstock fish reach twice that length, with males noticeably larger than females. Kamohara Blennies are robust fish, similar to the Striped Blenny rather than the delicate appearance of Blackline or Canary Blennies. These fish consume a diet of zooplankton in the wild, but aquacultured fish readily take pelleted and prepared foods.
