Turbinaria not growing

[magikfly]

I have a 3 inch wide turbinaria which just doesn't seem to grow.
It doesn't bleach either, polyps are totally extended all the time.
I've tried med light/med flow, high light/high flow
Anyone care to shed some light on how to make it grow?

How often do you feed?

 

[magikfly]

I never feed the corals, fish are fed once a day

Is this the yellow scrolling type or the pagoda cup?

My pagoda cup must grow 1cm a year or something. It is VERY slow.

The yellow scroll is definitely not a fast grower either but puts on an inch or two every year.

I have mine under around 450 par (med/high light) and VERY VERY high indirect flow.

A picture would definitely help.

You can see the turbinaria in the lower left corner
It's a crappy cellphone pic, but it's the best I can do right now.
It's directly under a Phoenix 250W DE

The picture is a bit washed out but it looks healthy to me.

Tonight, very late after the lights have gone out check the polyp extension. They should be massive. You want them to be dancing around a great deal. Try and shoot for flow that achieves this.

As far as light goes I do not think it would hurt to move it up higher.

What are the grow rate of other stony corals?

 

[magikfly]

Polyp extension during lights out is extraordinary, however I can't say that they dance around.
As for the other corals, growth is satisfactory given the fact that they're mostly just a bunch of stumps.
I'll move it up a few inches and see what happens.

I had this one for years and maybe got a little over an ich of growth out of it. It was almost half way up in a 60 gallon breeder under four 110 watt VHO's. It had great PE, but I never did feed it directly. Sometimes though, it would snag flakes or whatever frozen food it could get out of the water column. I just chalked it up to being a very slow grower.

you might have a turbinaria reinformis and I have found that they grow a lot faster than others in the genus. I don't neccessarily think polyp extension is an indicator of health but would agree that feeding them will help them grow better. I fed mine cyclopeaze and other plankton type foods.
