This is really only a half-truth. I am always a little confused by this argument even though it is a fairly common one that I see on the board at least once a week. There are a couple different things that I don't understand.
First, the chances of your clam surviving in your tank are much less than 50/50. This is not a toss-up 'maybe it will make it, maybe it won't make it'. I believe that there are some right answers in this hobby. These answers have come from people that have been doing years and years of research with this. While we are all learning new things all the time, that does not mean that all previous experience and knowledge is useless. You cite melevsreef a few times as an example where someone kept a high light clam under VHOs. There are, however, dozens of examples to the contrary. You focus on the one positive, because that is what you want to hear. Would you, for example, buy a car that got one good review and dozens and dozens of bad reviews? Of course not, that would be crazy.
Secondly, and more directly relevant to the quote above, do you understand why the clam survived in melevsreef's tank? What similarities does your tank and his have that make you think this is worth the risk? I could make the argument that I could take a little sports car up a rough 4x4 road because my friend took his big jeep up the same one. They are both cars, with 4 wheels, doors, and a steering wheel. But obviously, they are very different cars, and my little car probably isn't going to make it up the rough road. We all have tanks, but they are different. Using the logic that because one person had success where most others didn't, you might too makes no sense if you don't understand why that person had success.
Just my $.02
