Good moring
Apart from egg crate and glass what can be used as a cover to prevent fish from jumping out of the water?
Thanx

In the Koeberg blast radius
Perpex but you will lose light, and a decent canopy would be my bet on possibilities

Hi Joe - no - I am not too sure, BECAUSE you will require something that would allow the light to shine through from your light-units. IF you have metal halides, this can burst glass, and EASILY melt egg-crate....

So, I will be tagging along on this one...

Try a moon light at night. I used to have trouble with my discus jumping at night usually happens when the tank is pitch dark, with a night light and just a faint light in the tank cuts the jumping down as the fish dont get the initial fright.

The other option is to build the tank quite a bit deeper than required so that there is a decent wall of glass above water level...

Although I have heard of a rather large lionfish clearing at least 25-30cm!

Just to add, glass covers can not only build up heat problems, they can also hmaper the gas exchange at the surface of the tank, you can as Pterois said raise the sides up, either by taller tank or by fashioning a wooden bulkhead to match the stand.

A bit like this (was my buddy Kev's tank, i bought it and it is now sitting in my garage waiting for the stand to be built)

To add... my current tanks are all very tightly covered with glass and all sorts of things gaurding the overflow. I have lost to many wonderful fish to not have the tops and overflows tightly covered. I hear the arguments about light and gas exchange etc. but with the currently configured tanks I am not willing to mess about. Future tanks might be built with a better plan in mind... Sumps are open topped.

Ok.. because this is somthing Iv'e also been worried about since going open top for the 1st time on a tank.
Iv'e been cosidering using that plastic garden mesh that you get at Ben Bel/ garden shops etc. It comes in different mesh sizes. Cut to size with a frame round the edge would make it portable/ light and easy to fit remove. In my case I may have to lift the MH's though

Be careful, anything that isn't made of food safe plastic can leach toxins into your tank, it may also melt under the Mhs'
