Angelfish are a popular choice for aquarium enthusiasts, but deciding the right number of angelfish to keep together can be a difficult and often fearsome task. As mid-water swimmers, these fish require specific tank dimensions and setups to thrive. opposite to what many “experts” or fish enthusiasts may suggest, there is no simple, one-size-fits-all answer to the question of How many angelfish should be kept together in a given tank size.
Angelfish Quantity According to Tank Sizes
Here’s a quick reference table for the recommended angelfish quantities based on tank size:
Tank Size Recommended Angelfish Quantity
- 10 gallons 0 (not recommended)
- 20 gallons 1 (or 2 for breeding purposes)
- 29 gallons 2-3
- 40 gallons 2-3 (not ideal, better to choose a taller tank)
- 55 gallons 6-8
When it comes to smaller aquarium sizes, the options for angelfish are quite limited. A 10-gallon tank is simply not suitable for these fish, as they require more vertical space to swim and grow. The only exception would be if you’re temporarily housing small, child angelfish as they mature. However, this is not a long-term solution, as they will quickly outgrow such a limited environment.
How many angelfish should be kept in 20-gallon tank?
Moving up to a 20-gallon tank, the situation improves little. A 20-gallon high tank can potentially accommodate a single angelfish, provided it is the only inhabitant. However, mostly, 20-gallon tanks are better fitted for breeding, where a male and female angelfish can be kept together.
How many angelfish should be kept in a 29-gallon tank?
The 29-gallon tank offers a more workable option, as it can comfortably accommodate two, or possibly three, angelfish. This size allows for a bit more swimming room and the capacity for a small group, though it’s important to monitor for any aggressive behavior that may happen.
How many angelfish should be kept in 40-gallon tank?
A 40-gallon breeder tank, even though providing a decent water volume, may not offer the perfect vertical space that angelfish want. These tall fish thrive in aquariums with more height, such as a 40-gallon tank, which can easily accommodate three to four angelfish.
How many angelfish should be kept in 55-gallon tank?
The 55-gallon tank is often considered an option for angelfish enthusiasts. This size provides a large water volume, enough vertical space, and room for the fish to settle their own territories, if necessary. In a well-planted and properly decorated 55-gallon aquarium, you can comfortably accommodate six angelfish, and potentially up to eight.
Conclusion
Even though the recommended angelfish quantities based on tank size provide a general guideline, it’s important to note that these numbers are not fixed. Angelfish are cichlids, which means they can be territorial and aggressive, especially when it comes to breeding. The more angelfish you keep in a tank, the higher the chances of witnessing aggressive behaviour and potential breeding problems.
