The holiday darter (Etheostoma brevirostrum) is a small, colorful ray-finned fish that lives in freshwater. It's a type of darter, which belongs to the same fish family as perches. These fish are found in parts of the southeastern United States, including Alabama, Georgia, and Tennessee.
Holiday darters are known for their bright colors, which become even more vibrant during their breeding season in spring. They like to live in fast-moving streams with lots of big rocks and gravel. These rocks provide them with safe places to hide from predators and spots for females to lay their eggs.

Where the Holiday Darter Lives
The holiday darter can be found in specific river systems across Alabama, Georgia, and Tennessee. Scientists believe they live in about 18 different spots within four main river systems. For example, they are found in the Conasauga River and parts of the upper Coosa River system.
Sometimes, it's hard to know exactly how many holiday darters there are. This is because their populations can be spread out and counts can vary a lot. They are also affected by things like dams, which can block their movement in a river.
What Holiday Darters Eat and Where They Live
Holiday darters mainly eat tiny water insects and small crustaceans. They prefer shallow, clear streams with fast-moving water. Their favorite spots have lots of large rocks, pebbles, and gravel. These rocks are often covered with moss, and you might also find sand and river plants nearby.
They live in rocky areas and pools within cool or warm creeks. While larger fish might try to eat them, no specific predators are known to target only holiday darters. Their homes can be harmed by things like dams, which change water quality, or by dirt washing into the streams from logging or road building. Keeping the areas along the riverbanks healthy is important for these fish.
Holiday Darter Life Cycle and Reproduction
Holiday darters usually breed in the same areas where they live; they don't travel far to lay eggs. Spawning, or breeding, happens in the early spring, usually in April or May. During this time, the males become even more brightly colored, showing off shades of red, orange, yellow, or blue-green.
When it's time to lay eggs, the female finds a good spot, often between rocks or in a small crack. The male then fertilizes the eggs. After the eggs are attached to the rocks, the parents don't take care of them. Holiday darters typically live for about four years and can start having their own babies within their first year. If too much dirt covers the rocks, it can be hard for the eggs to stick, which can affect how many babies are born.
Protecting the Holiday Darter
Currently, there aren't specific big plans just for the holiday darter. However, it is a protected species in Alabama under special rules for non-game animals. Many holiday darter populations live in the Talladega National Forest. This forest helps protect their habitat and keeps their numbers safe.
National forests have special zones along streams to help keep the water clean and the habitat healthy. Filters are also used to stop dirt from washing into the streams, which helps protect the darter's eggs. The biggest threat to holiday darters is small dams that can separate groups of fish. Pollution and poor farming practices upstream can also harm their water quality and break up their habitats.
