Green to Brown

[Rodrigo_BG]

Any one knows why an intense green bubble tip at a LFS turns brown after a copple of days in our home tank?

I bought a beatiful green one and in one week its all brown.

All watter levels are just fine.

What kind of lighting do you have?

Sounds like it's gaining back it's zooxanthelle. Good luck on the anemone.

I don't think that is any light issue... 8 x T5 39w for a 45g tank.

Maybe the tank is too new (3 months)... I friend of my had the some problems, he bought 2 green bt's and both becomes brow into his tank...

Some hobbists states that the green with orange tips never turns brown... Mine is (was) the one with pink tips .

Anemones will turn brown and lose their photosynthetic pigments when their environment changes to one with less PAR. In most cases, if the PAR is increased their zooxanthellae population will drop, causing them to lose much of the brown color. Their secondary, or photosynthetic pigments will return. I don't know of anything other than lighting that can simultaneously cause zooxanthellae populations to grow and photosynthetic pigments to decrease. Maybe someone can chime in that knows something I don't.

Without knowing where your anemone came from, it's hard to compare your lights to the light it received in the wild. Your lights are obviously strong enough to keep your anemone alive. That doesn't mean they are strong enough to keep its color.

Hi elegance, thanks for your information... probably you might be correct. The anemone had come from a HQI tank, to my flourescents tank. Could be that... The problem is that there is no more room in my tank to add more bubls. Also HQI is not a good idea here in the hot Rio de Janeiro city.

But I also think that a mature tank, with a good watter quality could give hand on anemones green color
