When creating an appropriate environment for fish, we often don't consider lighting levels. Inappropriate lighting can reduce breeding activity. It may even reduce immunity & promote disease in some fish.


In research published this week in Biology Letters, a Royal Society scientific journal, NC State post-doctoral researcher Rudiger Riesch and colleagues found that Atlantic molly females from regular surface streams have a difficult time adjusting to cavelike conditions.

Surface female fish had trouble reproducing in the dark conditions, study results show. In addition, many surface-dwelling females introduced to dark conditions -- surprisingly, according to the researchers -- suffered from high incidents of stress-induced bacterial columnaris disease, or "fin rot," which causes patchy lesions on the bodies of the fish.

~ North Carolina State University (2011, June 6). Darkness stifles reproduction of surface-dwelling fish. ScienceDaily. Retrieved June 28, 2011.
