Seems to me it's a just a risk you have to accept if you want open-top. If you don't want to accept the risk, then you have to find a solution to make them fall back in the water "when" they do jump...

good points both of you.

The only sure way, it seems, to avoid fish jumping is to go with no fish at all. Herm. Food for thought indeed

There was a thread about this on RC a long time ago that got really long and probably 90% of people with open tops had lost fish unless the tank was only set up a few months. 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 ;-)

yeh my 90 is rimless and I to have had deaths inthe past. Thankfully only chromies ;)

Right and I agree 100% with what your saying. I just think especially for people new the hobby that they need to make sure they understand there is a risk. I am willing to bet if you keep an open top tank for say 5 years, even with just small peaceful fish, you are going to get some jumpers. If not, then thats awesome...but I think rare.

My scissor gobies would dive straight into the rocks when scared and never go near the surface, so I think your point about them having a safe spot in the tank like a cave is a good point. They should dart to that spot instead of out of the tank...hopefully.

I run open tops. I've had Gobies,Blennies,Mandarinfish, Yellow Tang, Royal Gramma,Wrasses,and Perc Clowns. I've only had one jumper when a friend put her finger in the tank, one of the Percs bailed. Bounced off her, and landed on the stand. Scooped it up and put em' right back in.
