The lifespan of a fantail darter (Etheostoma flabellare) is up to four years old in the wild.

How do they reproduce?

A male and a female become sexually mature by the time they are one or two years old, thereafter the spawning starts. Both males and females mate with multiple partners during this time. A male attracts a female with its bulbous egg-like dorsal fin.

Ideally, spring is the spawning season. The female nest 50 to 300 eggs per spawning season on the underside of the rocks to protect from predators. The overprotective male guards the eggs until they hatch into young darters.

What is their conservation status?

The fantail darter (Etheostoma flabellare) is listed as of Least Concern on the IUCN Red List. Being a riverine fish it is prone to microclimatic fluctuations like the temperature changes of the rivers and the changes in water level.

What do Fantail Darters look like?

Just after the eggs hatch and the young larvae become two to three days old, they become good predators and start hunting their food on their own. Due to fluctuating river temperatures and turbidity, their food supply diminishes making them repopulate to other places to maintain their diet.

Are they poisonous?

Fantail darters are harmless to humans but they are the keystone species of the rivers and streams. Hence, they are great predators of insects, fish, and other food. They nest beside rocks and gravel almost becoming invisible to their prey because of their sandy brown body color.

Would they make a good pet?

Since they prefer to stay around the river riffles, underwater rocks, and gravel, a similar habitat range is hard to create in a home aquarium. This may adversely affect their age and reduce the longevity of their life.

Also, for the spawning of the eggs, the males and females prefer staying near flat rock surfaces whereby the females can easily attach the eggs to the rock underside.

Hence, keeping them as pets at home isn't a good idea. Also, supplying them with food like insects, fish larvae, and nymphs to maintain their diet isn't possible at home.
