It also depends when it was doing that.
I just started my saltwater tank about 2 months ago. I kept a blue damsel for about 3 weeks before I made the regrettable jump to a clownfish and anemone. The guy at the store was dumb too.
I did not know about the water circulation pump, RO
water, the minimum salt levels, or the fact that the minimum was a 6 month waiting period before adding nems to the tank. I am getting the impression people like to take advantage of women's knowledge or lack there of in salt water aquariums.
I just bought a 2 bulb t5 but it won't be here until Thursday.
Long story short... my sabe anemone turns itself into a cacoon at night which I hear is normal. Is it only happening while the lights are off? Or is this in plane lighting?
