I hate this hobby.

OK here are some thoughts on this.

First of all to keep that type of anemone alive and thriving for so long is an achievement most people couldn't hope for, I would consider it a success and not a failure. The idea of a huge group of clowns hosting in that anemone I think deserves consideration, it would make a magnificent display. Another thought is that maybe after reaching a certain size these anemones become more predatory, if it is possible to make it split a few times (mechanically or by stressing it) you might have a more peaceful anemone as well as a few clones to sell, just a thought.

As far as losing an entire tank of corals it will happen to all of us sooner or later, it is the law of probabilities. Redundancy such as two half-powered heaters might help but eventually something will fail or a power outage will wipe out a tank. The best way around this IMO is an active network of people swapping frags, so if one person's tank got wiped out he could quickly restock his tank with frags from other hobbyists.

Anyway just my thoughts on this, my tank is young still and I know this will happen to me sooner or later.
