My 5 inch crocrea had beautifull coloring and now since I moved it to a 13 inch 40 gallon tank with a 250 watt metal halide pendent it has lost all of its spots. It teh purple blue color is the same just no spots. My calcium has been fluctuating a little but it has gone no lower than 380 and I got under control around 420. Alk is at 8.7 and magnesium is at 1260. Nitrates and Nitrites all 0. Is it because of the new lighting. I have been feeding it phytoplankton once a week. My other crocrea has lost some color but not nearly as much. It has changed from blue spots to green. What is going on? Oh also my clown is hosting in the teardrop.
