ricordia question

[SeaView]

Here is my situation. I had purchaced a large piece of rock with several ricordia shrooms on it. They were in bad shape, no color and almost completely white. I placed them in the middle of the tank and the ricordia slowly recovered to a bright flourescent green. At times, they would streghtch more then normal and I concidered moving the rock up, but due to the size this was impossible and they seemed to be doing fairly well for.

Now one year later they seem to be bleaching again. Why? The lighting, and possition are the same. Also some that are on the side of the rock and get less direct light are still green. Which really confused me. So is the problem not enough or too much light, or something else.

All the other shrooms seem great spreading like mad.

Any suggestion would be apprieciated.

lighting is 175 MH 10,000 k
NO actinic

I have found that the green ones don't seem to need as much light as yellow or orange and are very slow growers. I have some in a partially shaded area. If they were doing fine and now they seem to be bleaching where there is the most light I would ask if anything has changed? Did you recently change the bulb on your halide?

Good luck.

Hello
I have 3 ricordia in my 75 that i had gotton as very small from Premium Aquatics last year and They were a very light green color. I keep them in my tank about half way up and there under 4 VHOs and some days look better then others.. Think it was Jason at PA told me that they like sun and they also like a little bit of a current and to feed the some DT's and they would thrive under those conditions. which mine have...

I have some of the blue/green and some of the red ones. The red ones seem to like the light a little more than the green in my experience. I placed a green one about mid level under 250 halides and it basically disintigrated. I promptly moved the other two to a corner of the tank in less direct light and they seem to be doing much better. Not sure if yours are the "blue" which actually look like a blue green or the bright green.

I've kept all colors of ricordea under everything from PC to 400w iwasaki, and the best color I saw was under the 'saki. Bleached ricordea upon purchase is probably due to poor lighting/shipping or some other stress, and a ricordea bleaching under halide in your tank after purchase is generally a coral that was under poor light at the facility of purchase, in which case light acclimation rules apply. Ricordea here in the store is generally under 250 iwasaki, and loves it.

I have a 10g with 3 orange ricordia. they are located at the bottom of the tank under 72 watt PC. I bought 1 orange and 1 green polyp maybe 5 months ago. the 1 orange has split into 3, and today i noticed that one polyp has 2 mouths so i'll have 4 polyps soon. my green polyp was recently eaten by my peppermint shrimp which is still in the tank. im crossing my fingers (and feeding the shrimp).

Do you feed them? Mine eats like crazy almost as much as I give it.

Thanks for the replys -

As I said, nothing has changed it is the same set-up the ricordia recovered under and now 1 year later they are bleaching.

Ernie - I do not feed them directly, only incidently with the rest of the tank phytoplankton /brine shrimp. What do you feed and how much?

Thanks,

Steve
