• Hammer-headed euphyllia

  • Lisa

While browsing the topics of fellow forum members, I remembered that I wanted to ask something a while ago. I have a hammer coral of the Euphyllia genus, like the one in the photo. It came to me with several green hammers and all the others pink. I decided to wait, maybe they would turn green. It has been in the aquarium for six months now, or maybe even longer. The hammers remain pink. Does anyone know what causes the green color in this Euphyllia? Which direction should I investigate?

I think they are the same.

I found my photo.

If I'm not mistaken, it might be similar to acropoles - iron. And what kind of light is above it? And what is the depth?

Depth 40-45 cm, above the aquarium 2*150W 14000K + 39W Aquastar + 39W Coralstar.

The light is good. So it means it "overgrew" somewhere with yellow euphyllia. But only under actinic light does it give off a green hue?

only a few "hammers" (approximately the same number as when I arrived) FROM. maybe it should be like this, it's the euphilia from vadim_ya, many of them seem to have greenish hammers, and other forum members also have their euphilia with green hammers, so I became curious why this one is so deficient

Experiment with the lighting in terms of the blue spectrum. It may not be sufficient. The only lamp you have is a 39W Silvania Coral Star, and the rest does not contribute to the emission in the blue-green part of the spectrum. Therefore, your Euphyllia appears more light brown than green. However, for the green zooxanthellae to become dominant, a certain amount of time is needed after installing the necessary light sources. The bright green coral will not glow immediately, although it will no longer be as pale.

I can replace the aquastar with another coralstar... I'm sure I'll do it today.
