Now why???

[Rafty]

So I am new to this hobby. You would think installers would:

1. Tell you that fish that suddenly vanish may actually be in the overflow
2. Install a mesh to stop them jumping in

I looked in mine today and found a clown, perching fish and damsil that I thought died weeks ago!!

I am confused... generally an overflow has a grat so that fish do not get caught. You sure they did not jump?

BTW, you should learn everything about your tank -- how to take everything apart and put it back together correctly. If you are relying on someone else to do the maintenance, then eventually human-error will catch up to you.
This is definitely a hobby where preventive maintenance is key for long-term success.

There is a grate but they jump. I am trying to learn very about my tank including all maintenance and not relying on anyone but just starting out there is information overload and something as critical as putting a barrier to stop fish jumping into overflow seems like such an obvious thing to do and know about should have been part of standard practice and information handed over. That is just the way I would handled it now that I have learned from experience.

I am just a casual observer, no reef expert, but I think fish will settle down (not jump) if they have adequate rock-work to hide. Clowns will usually pick a small area in the tank and make it "all theirs" and are viciously territorial of that small area. Damsels are more free-water swimmers, but at night they do like a place they can hide (preferably down towards the bottom). If your fish are jumping, then they don't have adequate places to hide and they are getting spooked.
Also, not sure how your surface agitation is. Mine is pretty strong and almost none of my fish come to surface except occasionally a clown will come up and go right back down.

Rearragne your rocks to create caverns, crevices, etc. or maybe consider getting something like this so your fish have some place to hide:

I think I have heaps of hiding spots but they tend to cower at the overflow end and likely get spooked and jump. Since installing the mesh, problem solved.

A screen cover isn't a perfect solution either. Fish will jump and if there is a screen they can either get stuck on the screen and shrivel up or bounce out the tank. I know from experience. At least with it open fish will usually survive just a pain to get out

It's not a screen cover but rather a vertical wall extension of grill. The top of the tank is sealed so only place to bounce is back in the water.

Sometimes you have to learn the hard way. I've had many fish jump out over the years, and I have a cover but often forget to put it back on.
