There was everything from triggers to tangs to chromis jumping.

yeah.
Nobody refutes the fact that you're gonna have some jumpers if you go open top, its a gimme on this thread...lol
no question GSP, if you're tank is an open top, you will eventually lose a fish to it.
HOWEVER, I think this thread offers some great insight for those who understand the risk and just like or need open top for whatever reason.
and in my EXPERIENCE, in the 3 years I have been running open top reef s dedicated to PEACEFUL fish only, that your risk of jumpers is mitigated quite substantially by
A) Picking inhabitants carefully to ensure they will all get along, if you have even ONE single aggressive fish, your jump likelyhood increases significantly for every other one, this is why I gave my chromis, yellow tail damsel and yellow tang the boot in my 72 open top; aggression.
B) Have other places to go, if a fish has some known hiding spots like lots of live rock, they will have somewhere else to swim if a panic moment does occur
C) have your tank somewhere low traffic in your home

You'll never have a jump free tank, but you're certainly increasing the potential for one, even if your statistic leaves 10% of tanks jump free ;-)
