Making a jam jar aquarium
If a large glass tank is not available, practically any glass vessel can be used as a easy aquarium if it is well stocked with submerged water plants like as Elodea or Myriophyllum, to aerate the water. A 1 kg jam jar is fairly suitable for keeping caddis larvae, pond snails, small crustacean and plants like as Elodea and Lemna minor, and will keep in properly balanced condition for months if carefully stocked. It is as bad to under stock as it is to overstock.
