I've had my LTA for 15 years. No problems at all, been lucky. It's been through several tank upgrades and been stuck to the same rock all that time so switch overs have been easy.
Do I regret putting it in my tank? I voted Yes!!!! Only because I can't take it out as my wife would be ****ed as she likes watching the clowns live in it.
it is a good conversation piece for guests who come over and look at my tank. But I would like the space for other corals.
Don't feed them and they won't grow or split.
