1 Gallon Fish Aquarium. A gallon of freshwater at 392ºF or 4ºC and a specific gravity of 1000 weighs 83454 lbs. Its for tetras Danios and killies - fish that are torpedo shaped.
Fishbowls and small aquariums are not recommended for beginners due to the difficulties associated with keeping fish in them. I own a 5 gallon with a few guppies and shrimp and am merely curious about if a single or a pair of guppies can be kept in a filtered heated 1-3 gallon. The number of finned pets to stock in your aquarium depends on the size of your tank.
There are a few options available that will suit a 1-gallon tank though there are limitations on the number of fish appropriate for the small tank size.
Many of our aquariums are made from glass or acrylic. The weight of the water will increase directly proportionate to the weight of the salt being dissolved in the water. One of their suggestions was goldfish. 30 5 x 15 2 x 20 3.
