While some buyers were pleased with the Aqueon tank, others reported that it came damaged or broken.
Shipping issues are typical, but the Aqueon received so many complaints that we couldn’t put it higher on the list. Although package damage may occur when it is mistreated, the Aqueon’s problems seem to be the result of a design error rather than a heavy-handed delivery driver.

Is a 20 gallon fish tank sufficient to get started?
A 20-gallon aquarium will enough for most fish unless you want to raise feeder goldfish (fish bought to feed other animals) or other large-bodied fish.
How many fish should a 20 gallon tank have?
A gallon of water for every inch of body length is a good rule of thumb. I disagree since the fish’s swimming behaviors and disposition are just as significant as water chemistry and filter load issues.
First, each kind of fish like to be at a specified depth in the tank. Some will never reach the top, while others will remain in the middle or upper echelons.
Swimming speed is another factor to consider. A feeder goldfish, for example, is just as healthy and lovely as a pet goldfish. They also develop swiftly and are good swimmers.
Unfortunately, goldfish may be highly shy and can batter against tank walls as hard as they can during thunderstorms or when frightened.
Even a 3″ goldfish may smash itself hard enough to cause major internal harm and death in a 20 gallon aquarium.
Tiger Barbs are little fish, but they need a lot of space to swim and school. A tiny tank may create tremendous stress and increased hostility.
The tank is too little for even one goldfish in terms of size and temperament. It’s approximately appropriate for a school of 6 – 12 tiger barbs, as long as they’re not kept with other fish that they could harass.
What is the largest fish that can be housed in a 20 gallon fish tank?
This is determined by whether the fish has to be in a school and how active the species is. I’d suggest keeping mature fish around 2.5″ in size to ensure each fish has adequate territory and space to dart without being hurt.
Because transferring fish from one tank to another might be problematic, it is preferable to get a tank large enough to accommodate all of the adult-sized fish you want to maintain in the tank.
Plants function best on a 20-gallon container?
Many plants that benefit low-light conditions can help this size of the container. If you intend to keep a 20-gallon tank as well as load it up with online plants, you can opt for the following ideas:
- Amazon swords
- Java moss
Can I also put snails and shrimp in a 20-gallon tank?
Yes! You will certainly discover it beneficial to put snails and shrimp in storage tanks since they can eat up the majority of the algae as well as other small food items that your various other fish may not need. They can be wonderful for balancing the ecosystem inside your fish tank configuration.
To wrap it up, our top pick is the Marina LED Aquarium Kit due to its energy-efficient LED lighting, the incorporation of a clip-on filter, ease of setup as well as setup, good dimension, as well as the inclusion of different fish maintaining products to obtain you started. While others are all right for being a 20-gallon tank, this one is typically better due to its beginner-friendly plan and friendly customer guidelines to aid you start on fish maintaining.
