Our class project is up and running. 29 gallon biocube with Ecoxotic LED Pro retro kit and an Aquatic Life mini skimmer. The LFS had a Clarkii hosting an anemone. Although the Clarkii wasn't my first choice, seeing this symbiotic relationship in our tank was too much to resist. That being said, are we out of luck with adding any additional clowns? If we do add any more clowns do they have to be a smaller Clarkii? Any input is appreciated.
