Fun Blue-spotted Sunfish Facts For Kids
Gallery
The sunfish is a popular family of a large number of New World fish that are generally endemic to North America. The blue-spotted sunfish, also written as the bluespotted sunfish (Enneacanthus glorious), is one of the least famous but most colorful and attractive small sunfish.
Its distribution extends to the eastern and southern parts of the United States and the distribution of this species is almost native throughout its range. This freshwater fish also might end up in a home aquarium as they make wonderful pet fish.
They are difficult to differentiate from another member of the sunfish family called banded sunfish. In the aquatic world, hybridizing these two fishes is not rare.
Bluespotted sunfish have a wide distribution and their distribution is relatively easily found throughout their native range.
The most preferred habitats of the bluespotted sunfish species are freshwater ponds and lakes but they can also exist in sluggish and brackish aquatic bodies and don't forget that blue-spotted sunfish are loved as pet fish too. If you are interested in knowing the life, history, and nature of this fish, keep on reading these interesting facts.

Where does a blue-spotted sunfish live?
Like all sunfish, bluespotted sunfish are found in North America. They are a native species of the coastal lowlands of North America that extend from the southern tip of New York to further south to the western borders of Florida.
In Florida, these fishes populate the peninsular drainages of western and north-central parts. In the north, the distribution of this aquatic freshwater fish ranges up to New Jersey and Pennsylvania.
Some common river basins and drainages where they naturally occur are the Yellow River, Suwannee River, Tampa Bay, minor Gulf tributaries, lower Mississippi, and the Escambia River. Part of its population has also been introduced in some freshwater lakes, such as Ontario Lake.
What is a blue-spotted sunfish's habitat?
The bluespotted sunfish stays in mud pools or backwaters containing lots of vegetation where underwater observation is relatively difficult. This makes gathering knowledge about the life history of these fish in their habitats quite difficult.
If these fishes are kept as pets, a blue-spotted sunfish aquarium must contain cold water for them to breed in and the aquarium environment should imitate the clear and slightly acidic water of this fish's natural habitat.
Who does blue-spotted sunfish live with?
The bluespotted sunfish turns aggressive and hostile if kept together in a tank with other species outside of the sunfish group. They prefer to stay only with their own species and with other sunfish.
How long does a blue-spotted sunfish live?
The bluespotted sunfish do not have a long lifespan. The northern species can reach a maximum of five years of age but fish in the south cannot even live that long.
How do they reproduce?
The bluespotted sunfish attains sexual maturity at different ages depending on its body length and location. For example, northern fish mature at a comparatively larger body size than southern ones. Northern bluespotted sunfish start their gonadal growths from an earlier stage.
The breeding season lasts longer in the south than in the north due to differences in water temperature. A male builds the nest for a female near vegetation.
Spawning occurs multiple times in a season and some days it occurs for long periods. The females produce 42-216 eggs in a single clutch and the male guards the eggs. Both male and female blue-spotted sunfish care for their fry until they are mature enough to take care of themselves.
What is their conservation status?
The bluespotted sunfish species has been classified as a species of Least Concern in the IUCN Red List. The fish occurs in abundance throughout its native range and is currently not threatened by any major threats. Their status is currently not protected by any management authorities owing to their large population.
