My LT was buried in the sand with it's foot attached to the bottom glass. It was under a ledge and inflated out into the open in front of the ledge. It needs rocks surrounding it to feel secure I guess. That was my experience. It thrived in a 75 under 8 40W NO
tubes for a couple years and spent the last several years under 175W MH
. Had it for around 12 years. It survived 3 tank moves.
In the last year it slowly shrank from a max inflated disk diameter of around 12" to nothing. Interesting but perplexing. It was incredibly healthy until then. Even as it shrank it appeared healthy. I think it may be a case of the tank's environmental dynamic changing. It seems like some things thrive while others fade away. Then a few years later, that which thrived begins to fade and something else thrives. I've noticed this in other tanks as well, especially mature tanks. The closed environment we attempt to keep seems to be in flux as we add things, change things, move things, etc.
I haven't been tempted to replace it for the reasons I preach here. Also if one anemone died, why wouldn't future specimens? All the corals I have come from cuttings & frags
. Fragged corals don't impact the environment. I'm not a tree hugger but I've seen some pretty ravaged coral reefs and this hobby, for the most part, ain't helping. blah, blah, blah, preach, preach (falls off soapbox)
