screen lid

[markonen]

I have a small 5.5 gallon aquarium that I would like to fit with a nice and simple screen lid.

I'm willing to get together the raw materials and make one (if it isn't too hard and the price is right) or buy one (if the price is reasonable).

Anyways, I have the following questions to ask:

1) Is it generally worth it to make a homemade screen lid?
2) Are there plans/instructions for making screen lids on the internet? Where could they be found?
3) Do screen lids typically fit snuggly into the opening or are they attached somehow?
4) What would be the price for a very plain screen lid for a 5.5 gallon aquarium?

I'd also appreciate any general advise regarding fitting an aquarium with a screen lid. Thanks.
