As above described acting nature leads to the fact that during the entire yearly polyps in most different colors are found. The natural mutation leads to the fact that there are not always directly many polyps of an identical color. |
thanks for your info heinz. i have a few questions.
First is why do you feed phytoplantkon instead of zooplankton to your ricordias? I have noticed in the past I get a much more vigorous feeding response from my ricordias when feeding a larger zooplankton mixture. I also would like to know what type of species of phytoplankton you are using. I have only cultured Nannochloropsis and Isochrysis in the past.
My next questions are regarding the coloration changes you have observed. You have noticed a natural coloration change in the polyps according to seasonal variations and other variables, why do you suppose coloration of ricordia polyps seem stable in captivity. Other than having observed polyps that were not well taken care of exhibit bleaching and the "transparent" or white color I have not noticed any major color variation in my yuma or florida specimens in the past even under different lighting or tank depths int he past. Maybe differences in intensity of color but not an actual color shift.
As always, great getting to read your input and experiences
