good thing my tank is still in planning! i am big into researched and not so researched experimentation! some ideas stolen from the internet, mixed with a thought!
Coral - algal symbiosis. A key component of coral physiology. Coral cells contain endosymbiotic dinoflagellates (Glowing dino flagellate springs to mind
) of the genus Symbiodinium (Yep, it is the wrong genus
Dinoflagellates convert sunlight and carbon dioxide into photo synthetically fixed carbon, most which is translocated to the coral host, and enhances coral calcification. Reef building corals live in oligotrophic tropical waters with high solar irradiance and warm seawater temperatures, which promote high rates of primary productivity. Moreover, the coral skeleton augments the amount of light within coral cells as compared to irradiance in the adjacent water column. Dinoflagellates, like all photosynthetic organisms, must maintain a delicate balance between the sunlight harvested and processed through photochemistry.
Changes in light and temperature are among a suite of environmental variables that can create an imbalance and ultimately lead to dissociation between the coral and the dinoflagellates (YES, thats right, kill off the natural ones and replace them with, you guessed it = GLOWING ones!)
there is a bacteria too! LOTS more to read up on and who knows what I will try! Probably will still be a clown fish LOL no harm in a bit of reading though!
