I am having a problem (i think) with my some of my zoas. I do not feed them anything and I think that might be the problem, here is why:
I have 5 small colonies, from 3 different sources. They all looked great when i got them all between 1-3 months ago. Now the watermelons and purple with green skirt (dont know name) dont look as good. The watermelons gree like crazy the first 2 weeks and have since just really spread out an now the polyps dont open near as much, and they are losing some colour. They have not moved since i put them in. The purple zoas are losing colour as well, but only the ones that point up towards the light, not on the bottom of the rock. The other three colonies look fine. All colonies are 4" from the bottom 6" apart from one another in my 18" deep 75G. I am thinking that based on placement, these two colonies are not getting enough flow and hence not enough food, or possibly enough flow, but still not enough food.
Here is my setup
75G with 20g sump and in sump marine sources skimmer that works well. I run a filter sock about 50% of the time, usually after a water change, which is 5G once a week.
My SG is pretty solid at 1.024 and alk goes from about 8.7 to 9.2 and calc from 410-440, mg is around 1280. I do not measure phosphates and have not checked nitrates in a long time cause when i did i would always get as close to zero as i could measure. I have 4x 54w t5ho lamps that runnfor about 6 hours a day. I have a very shallow sand bed (just covers bottom glass). I have prob 75-100lbs of rock in the DT. I also have a small montipora dig. Frag that darryl gave to to try that is growing like crazy. Oh temp is 79 or 80 all the time. I think thats everything.
What do you guys /gals think? What should i feed if that is problem?
