Here are a few reasons why a scissortail rasbora needs at least a 20-gallon tank:
- Scissortail rasboras are active swimmers. They need plenty of space to swim around to stay healthy and happy. A 5-gallon tank is simply too small for these active little fish.
- Scissortail rasboras are schooling fish. They do best when kept in a group of at least 6 individuals. A 5-gallon tank is too small to provide enough swimming space for a group of scissortail rasboras.
- Scissortail rasboras can be territorial. Males may become aggressive towards each other in a small tank, especially during breeding season. A 20-gallon tank provides more space for the males to establish their territories and avoid conflict.
- Scissortail rasboras need plenty of plants. They love to hide among plants, and they also use plants to spawn. A 5-gallon tank does not provide enough space for a variety of plants.
In conclusion, while it is possible to keep scissortail rasboras in a 5-gallon tank, they will be much happier and healthier in a larger tank, such as a 20-gallon tank. If you are considering getting scissortail rasboras, be sure to have an appropriately sized tank to provide them with the best possible environment.
