I pretty much have a FOWLR
tank, but bought a mushroom coral rock to see if I could keep it. My lighting is 1 10,000 k
bulb, 1 actinic and 1 generic hoodlight that came with the tank.
The Mushroom rock has generally done great for a month ----most days all 8 `shrooms
appear swollen and healthy. Every once in a while I get a day where one seems kind of shriveled and dis-colored. At least 1 time this has happened after a water change.
I always think that its on its way out, but they always seem to bounce back in a day or so.
I was just wondering what may cause this type of behavior.
thank you for input.........
