Coloring up green grandis

[Supreme Reefs]

is there a certain way to make you green grandis color up? heres mine

i have heard there are ways but not sure if its true... anybody have any tips to make them color up?

I am not an expert by any means, bt I love the Polythoa Grandis.

I am thinking that it is not that far off in color. But, maybe a little LESS light. or lower in the tank...
Look up cinnamon polyps

They MUST be fed. They will not do well if theya re not fed. They are a deep water protopaly from the Gulf of Mexico that live in low light (can easily be acclimated to higher light levels with no ill-effects) and nutrient rich waters.
Best foods are finely chopped krill, silversides mixed with mysys, brine shrimp and daphnea. Feed twice a week and you will see an improvment in colors and growth.

Here are mine. They do best in my tank on the sand about 30 inches from 2 x 15W 14K. They do like to be fed as mentioned.

i try to feed all my polyps, if they close up around the food, i keep on feeding them, (about 1-2 per week)

These do 'eat'

BTW: going rate for these at lfs in the SO CAL area are between $35-55 per polyp

I have kept them under all intensities of MH. You can tell what they are wanting. If they are folding up, barring there is not too much flow on them, they have too much light. Right now I keep them about 15" from 250wt 14K MH. They were acclimated to this intensity over 4-6 months time.
Moving them around will not irritate them once they have settled like many other zoanthids, though protopalys rarely become as irritated like many palythoas and some zoanthus do.
You can experiment to see where in the system they color up the best, but as stated before, direct feedings of meaty foods are the most improtant for this and basically all protopalys.

O_O wow those are nice! i tried feeding them before but they wouldnt take anything i tried mysis and brine but ill try again. yeah i guess mine doesnt like high lighting like flric said they curl up when they have too much light. ill go feed them righ tnow are these protopalys slow growers?

i feel like it will bite off my arm :neutral:

Sort of. Mine are growing an average of 2 polyps a month. Not as slow as many other zoanthid types, but much slower than most.
I would be suprised if they did not feed. Protopalys are little piggies when it comes to taking meaty foods. Try some chopped silversides too.
I have been trying the Rod's Coral food. So far my zoanthids seem to be accepting it, well, palythoas and protopalys that is. Zoanthus don't readily feed on larger food stuffs.
Forgot to mention that a quality zooplankton added to food you are using does seem to get better results from all zoanthids. Target feeding them allows them to take either the zooplankton and/or meatier foods.
The Rod's seems OK, but for the price I think once this pack is used up I will go back to dropping a frozen chunck of silverside, krill, mysis, brine shrimp, daphnea and whatever else I have on hand into a blender and turn it into mince, then add some zooplankton and after it comes up to tank temp feed this for a much better cost savings with just as good results.

I tried feeding them this time with bigger chunks of meat brine and mysis and it accepts it :bigsmile:. So 2 times i week is good? is there a such thing as overfeeding them or they will just stop accepting food when theyre at thier limit? i have had mine for almost 2 months now but still no growth. Although this was the first time it has been fed.

I would guess they would not take the food if they did not need it. Mine have taken food each time, but I have never tryed feeding more than 2 times a week.
Watch them start growing now.

mine readily accept pellet food...
I find that under higher light I get a green result whereas where they are now they are the traditional brown and white cinnamon polyp

i took a look today and i think i see a little nub on the bottom of it so im guessing its gona be a baby soon :bigsmile: thanks for the tips

pellet food hmm ill try that too. i have some color enhancer pellets i hope they work for corals as they do with some fish.

I would be careful with pellet foods. Some have addatives to preserve. Many contain phosphates and do you know beyong a doubt what is actually in there. Certainly wouldn't feed anything to my tank if I thought for even a second it was made in China.

I am the new guy but I have to throw in my 2 cents worth. Yes feeding is a must. I feed mine Mysis mostly. They get tan under higher light but under a little less intense light mine get a pale blue. The ones in the photos are actually Caribean Grandis and not the Palythoa Grandis.

All of them are Caribean Grandis? What is the difference between those 2?

This is my understanding and am always open to learning new things, so if I am wrong let's discuss it, I want to learn.
Every photo I looked for under Palythoa Grandis was Caribean Grandis. My one polyp did not make it so I will have to look in past photos. My LFS has a Palythoa Grandis that is blueish in color and the polyps are as big across as baseballs. They told me it was True Palythoa Grandis. I got a one polyp frag from somewhere else. The store colony is NFS. I will do some research and get back to you.
