Duplicislontus xylunta
This species evolved after some O. maculatus swam out of the channel of zone 23 and into zone 4. They remain as a cleaner, helping remove the Phytovorus poliosa from the A. greenesnis. They help keep the plants clean from the fungus growths, as well as occasionally eating all of the infected segment. They stay small, only 7cm, but due to living inside of the A. greenensis they are mostly sheltered from predation. They reproduce with small batches of eggs, only around 7-13. They retain many of the same physiological qualities as their ancestor, although they have adopted a green color to blend in with the A. greenensis, and growing a 2nd pair of identical fins directly behind the first, which allows them to swim faster in case they are seen by a predator.
