duncan coral

I don't know which subgroup this goes in.... I just purchased a green duncan as I got a great deal on the frag. I thought it needed medium light and medium waterflow. But different websites have said it will only live in really strong flows.

I was confirming whether or not it needed calcium. I does. I put it near a power head without the flow pointed at it in the middle of a taller rock. My setup is a 4x65 t5HO.

 

It will do OK in medium light, medium flow. Mine is in low flow and it has gotten so big that I have to move it because my large frogspawns are stinging it.

 

I can move it. It has free range in the tank.

 

Both are open but one head I can't see its oral disk some of the time.

 

low to medium flow IME

with my T5 I had to keep them on the substrate.

 

My experience with them is either high flow or medium flow is fine. It will effect how the tentacles grow. In a higher flow environment they will develop longer tentacles and if in a lower flow the will be shorter. If acclimated properly they can take whatever light you though at them, I had them about 8 inches from the top of my 75g under 250W MH.

Also are you sure you mean t5HO? I dont think they make that wattage, it sounds like Power compacts to me.

The sub-category would have been LPS but both work!

 

You are correct they are 54's. I thought they were lps because they require feeding and calcium. I fed it today I tried dropping some flakes on it and it closed up before I took a shower this morning. When I got back the polyps were open again.
