lid or not?

should you use a glass lid on a planted aquarium with active fish? I have a 29 gallon high tank with various tetras, raspboras, rainbowfish, cory cats and kuhli loaches.

I recently purchased a t5ho light fixture that sits a few inches above the tank. I would like to know if I remove the versiglass top if I will have a problem with fish jumping out of the tank.

I've had some of my neons jump out of my tank with no lid. Chances are good that you can loose a few like this.

Agree with without a lid may eventually feel inclined to jump, even if they do not jump for a long time. Floating plants can help in discouraging fish from taking 'the big leap', but a lid is the only surefire way to prevent (or halt) jumping.

I doubt of Tennessee is as dry as Colorado but without a lid I would have to top off my tanks everyday due to evaporation.

The wheel turns.

Agree. I had a few jumpers before I put a glass top on. The first was a neon that jumped in the middle of the night and was found by my daughter when she went to do her morning fish count. The second was a diamond tetra that jumped one evening while I was sitting next to the tank reading. I heard a small thump on the floor and looked around to find him. He was safely put back in the tank and is still going strong. The last one was another of the diamonds. Fortunately, my daughter saw it and got to it before any of the dogs.

So how much lid versus open area for oxygen exchange?

For example, on my 45G I have a lid or light on about 80% of the tank, then a small section near the plumbing open for air exchange.

Some people use egg crate for jumping fish in those areas, I haven't so far.

But... how much open area does one need?
