Neon Goby
Elacatinus oceanops
Neon gobies have blue and black horizontal stripes similar to cleaner wrasses of the genus Labroides.
The so-called Cleaner Gobies are found in the Caribbean from south Florida to the Bahamas and the Bermudas.
There are few external differences between the sexes. Females will usually be a bit larger and plumper than the slimmer males.
