Gboy - there's not necessarily any motive: people on the interwebz tend to be a-holes simply because its the internet.
I'll tell you a brief, off topic story, to depict said point. I recently listed an ipad for sale on craigslist. This means that I was trying to sell said device to the open public with no real punishment for poor behavior. On ebay, your reputation can at least take a ding, or paypal can pull back money etc...but CL? Its the worst of the worst.
So I'm selling this thing at what I considered a very reasonable price: around 50 bucks less then what apple would have charged for a refurbished but identical model...and I was throwing in a case. Had a buyer all lined up, we'd negotiated etc. Guy shows up and says "Ok great...but I only have *amount we'd agreed upon minus $150)". Needless to say I walked away with ipad still in tow, and pretty pissed off - but there's no way for me to "get back" at the dude.
Same thing with taking advice on the internet - someone could tell me that I could keep a bamboo shark in my 72. Now odds are good that 50 other people would jump in yelling "dont do it, that guy is a moron" - but there's no culpability when the internet is involved.
I used to be a very active member of a few usenet groups (rec.sports.paintball in particular) and just like craigslist the number of total jerks that you would run into there were staggering. I had lined up an internet team at one point to play a paintball event, using that group - and guess what? After driving to toronto, one of the guys "couldnt make it". Same thing - the dude was an a-hole, but at the end of the day I couldn't do much to him apart from posting to the same group that Dude XYZ screwed me over.
Anyway, that's all I'm saying: and while normally I wouldn't trust LFS, this particular one has helped me out a ton, thrown me free help when I've needed it, and hasn't really led me wrong. The CBB situation sucked, and it's always miserable when a fish dies, but at least he made it right by me.
In other news, I dove in with that aiptasia X - my son got a real kick out of watching it go on. Zapped about 10 of the buggers...couple more on the underside of the rock that I'll try to get to after I see how effective the stuff was on the ones I nailed. There was something incredibly cathartic about zapping the little buggers
