hting, and slow-moving water will suit them.
Bumble Gobies
Bumble Gobies is another species for the hobbyists who want the best fish for a five-gallon tank. They are more suitable for saltwater tanks even though they can survive in freshwater. These fishes grow up to 1-1/2inch at max, and you can place a few of these in a 5-gallon aquarium. Bumble Gobies can be aggressive towards other fish species and should ideally be placed with their own species. They do well in tanks with a pH of 6.5-8.5 and temperatures from 71 to 84°F. The water must be regularly filtered while maintaining proper salinity levels for keeping Bumble Gobies.
Dwarf Puffer
Dwarf Puffer is a small-sized fish species for the people who want the best fish for a five-gallon tank. It is an energetic fish that grows up to 1-inch in length. These fishes tend to be aggressive and don’t do well with other fish species. You can place one or two dwarf puffers in a single five-gallon tank. Aquariums with a sand substrate are more suitable for them though they do fine in gravel also. They prefer a temperature of around 75-82°F with 7.0 water pH level. Adequate plants and decorations that provide hiding spots should be available to the Dwarf Puffer in the aquarium.
