If you are planning to get a pet there are a few things you should need to know, and one of them would be its enclosure. Enclosures are an important thing for your pet because this is where they’re going to live.
This article will show you what animals would fit in a 20-gallon tank. If you manage to spot your kind of pet on the list, then it’s a clear sign that you should purchase a 20-gallon tank for them as soon as possible (if you don’t have one yet).
Yes, an Angelfish can live in a 20-gallon tank.
Since Angelfish is a kind of fish that belongs to the long and large size category, it’s only right to give them a tank that would cater to their size. As we delve deeper into their size and shape, it’s important to note that as they grow, they tend to grow long and not wide.
Their fins mostly make up their size and these grow laterally, so it would be best to get a tall tank rather than a wide tank. A taller tank would also make more room for decorations and substrate (the soil inside a tank).
Angelfish are okay with living with other fish, so long as this is their kind. Angelfish tend to get aggressive if they get grouped with other kinds of fish.
Moreover, if you plan to put them alongside other Angelfish, then the maximum number must only be four. Otherwise, the Angelfish will start to become aggressive and territorial because of overcrowding inside the tank.
Multiple Angelfish shouldn’t share a single 20-gallon tank, it’s going to be too cramped inside said tank and that would lead to aggression from the fishes.
Only a single Angelfish can be placed inside a 20-gallon tank. If you would like to add one more Angelfish then you must add at least 10 to 15 gallons worth of tank space. So the average gallon capacity for two Angelfish would be 30 to 40 gallons.
Yes, but only baby Bearded Dragons can live in a 20-gallon tank.
Bearded dragons grow fast and when they reach their adult stage, they can measure up to 20 inches long. A 20-gallon tank wouldn’t be enough to accommodate this kind of size and it would only put a Bearded Dragon under a lot of stress.
The tank size of a Bearded Dragon would depend on the size of the animal itself. If the Bearded Dragon was bought as a baby, then they can easily fit and live comfortably inside a 20-gallon tank. However, the same can’t be said as they grow older.
As aforementioned, these animals grow quickly, so as owners, you must purchase a bigger tank if you only have a 20-gallon tank for your Bearded Dragon.
It would be wiser to purchase a 40-gallon tank on the get-go so that it can cater to your Bearded Dragon’s size from its baby stage up to its adult stage.
No, Oscars can’t be kept in 20-gallon tanks as this size is too small for them.
The average size of a fully grown Oscar would be 12 inches and a 20-gallon tank is too small for that. The ideal tank size for an Oscar would be 55 inches, however, it would be better if their tank size would be upgraded to a larger capacity of 75 gallons.
The 55 to 75-gallon tank size would only be fitting for a single Oscar, however, the situation would change once you decide to add another Oscar. Two Oscars would need to have a 100-gallon tank so that they won’t be stressed, ill, and aggressive in smaller tanks.
An additional 20-30-gallons would be needed per fish.
No, chameleons can’t live in a 20-gallon tank because it’s too small for them.
Chameleons are medium-sized reptiles and they require large enclosures where they can freely roam around to maintain a healthy life.
Moreover, their enclosures must have enough ventilation for them to survive. The ideal tank size for chameleons would be 29 gallons.
Yes, you can have two female Bettas in a 20-gallon tank.
Two female Bettas can live comfortably in a 5-gallon tank, so what more if they were provided with 20 gallons worth of tank space? This would be great for two female Bettas because they get to swim around inside a spacious tank.
Yes, a full-grown Corn Snake can live in a 20-gallon tank.
When you’re looking for a 20-gallon tank for your Corn Snake it’s better to get one that’s large in width than height. A wider tank is always better for snakes.
Yes, hatchling and juvenile King Snakes can live in a 20-gallon tank because it provides enough space for them.
The moment King Snakes grow and become adults, they would need a bigger tank/terrarium. The ideal size for adult King Snakes is 40 gallons.
Six Minnows can comfortably live in a 20-gallon tank.
One White Cloud Minnow should be provided with a 10-gallon tank size for this is the ideal size for them. Any additional fish would require 2 gallons of water per fish.
Only one adult turtle can live in a 20-gallon tank because multiple turtles can outgrow 20-gallon tanks once they reach their juvenile and adult stage.
There’s a general rule of thumb when it comes to buying an enclosure for turtles and this is getting 10 gallons more of tank space per turtle that’s being added in an enclosure.
Only more than one hatchling can live in a 20-gallon tank, but as soon as they start to grow (and this growth happens very fast) owners would need to get a much bigger tank as soon as possible.
Only one Angelfish can fit in a 20-gallon tank.
Angelfish is a big type of fish so a measly 20-gallon tank won’t be enough to accommodate its size. Also, it would be a terrible idea to make this fish have any companions, especially inside a small 20-gallon tank.
The results would be horrible. The Angelfish would start to show signs of aggression and being territorial, so they will most likely end up hurting other fish.
Pajama cardinal, Watchman Goby, Purple Firefish, Clownfish, Bangaii Cardinal, Yellowtail Damsel, and Royal Gramma Basslet are saltwater fishes that can live in a 20-gallon tank.
Mostly the list of fish that can be placed inside a 20-gallon tank is small fish. The fishes we’ve mentioned don’t grow as big as Angelfish or Oscars.
A 20-gallon tank would be ideal for them but anything smaller than that would make things worse.
Four to five saltwater fish can be placed inside a 20-gallon tank granted that they are within the 2-3 inch size chart. If they are smaller than this measurement, then you can add more fish inside the tank.
However, size shouldn’t be the only factor being looked at here since you also have to take into consideration what type of fish you’re going to be putting in the tank. Some fish aren’t comfortable living with a specific type of fish.
An Angelfish would be the biggest fish a person can put inside a 20-gallon tank.
Although there are some that argue that an Angelfish is too big for a 20-gallon tank, these fish can still live comfortably in 20-gallon tanks.
However, if people have the budget to upgrade their tank size for an Angelfish, the better. There are also numerous people that claim that only nano-sized fishes can comfortably live in 20-gallon tanks. A nano fish’s maximum size would be three inches.
It would take 30 to 36 hours to warm up a 20-gallon tank.
The right temperature inside a tank would add up to the lifespan of a fish since this keeps them healthy and reduces any likelihood of getting stressed. Furthermore, the right tank temperature would contribute to the overall well-being of a fish.
Yes, you can use a 10-gallon filter for a 20-gallon tank, however, you must know that it can’t fully accommodate a fully-loaded 20-gallon tank.
Since a 10-gallon filter can only provide adequate benefits for a fully-loaded 10-gallon tank, not much can be said when it’s applied to a larger tank, in this case, a 20-gallon tank.
Yes, a 20-gallon long tank can fit a 29-gallon stand.
Since 29-gallon tanks can even fit 20-gallon stands, then surely the same could be said vice versa. So you shouldn’t need to worry if your tank and tank stand’s sizes don’t match up.
A 20-gallon tank should be cleaned every week or bi-weekly.
Of course, apart from the size of the tank (larger tanks are harder to clean), other factors should be taken into consideration such as filters.
Filters can also determine how often one should clean a tank. For instance, if you own a high-quality filter such as a chemical, mechanical or biological filtration system, then you can clean your 20-gallon tank at least once a month.
The price range for 20-gallon tanks would be $50-$200.
The cost of a 20-gallon tank would be dependent on what brand it is, what material it’s made out of, and the inclusions it has (if applicable) such as a heater and a filtration system.
The Tetra Aquarium 20-Gallon Fish Tank, Tetra Aquatic Turtle Deluxe Kit, and Exo Terra Outback Terrarium would be the most popular 20-gallon tanks.
