Yellowfin Shiner

Overview

Yellowfin Shiner (Notropis ultipinnis) is a middle-to-top swimmer for aquariums where the layout leaves enough open swimming space and the water stays stable.

Use these values as planning checks, then make sure the aquarium still has room for behavior, group needs, and calm community fish.

Care requirements

With a Beginner – Intermediate care level, Yellowfin Shiner is approachable, but it still needs stable water, clean substrate, and a well-planned stocking group.

Because it uses the middle to upper part of the aquarium, leave enough open swimming space instead of crowding that part of the aquarium.

Plan the aquarium around the group, not just one individual.

With a lifespan of up to 2 years, this is a fish to plan for long term rather than an impulse addition.

Aquarium size and space needs

An aquarium of 80 L or larger can be a reasonable starting point, but it should not be read as permission to overstock.

At up to 6 cm, Yellowfin Shiner stays small, but a group still needs room to move, feed, and avoid constant competition.

Uses the middle to upper part of the aquarium, so leave enough open swimming space for movement and feeding.

A group of 6 or more should have enough open swimming space for movement and feeding.

Water parameters

The temperature range for this fish is 10 to 23 °C, which fits many tropical freshwater aquariums. Choose other fish with overlapping temperature needs.

The pH range for this fish is 6.5 to 8. That points to a broad freshwater range, but stability is more important than sudden corrections.

The GH range for this fish is 10 to 25 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.

Temperament and compatibility

As a peaceful middle-to-top swimmer, Yellowfin Shiner is best kept with calm species that will not harass it or dominate the feeding area.

If kept in a group of 6 or more, the aquarium should have enough open swimming space for the group rather than being planned around a single fish.

Because this fish uses the middle to upper part of the aquarium, compatibility is easier when other fish are not all competing for the same swimming space.

Swimming zone and behavior

This fish uses the middle to upper part of the aquarium, so leave enough open swimming space for movement and feeding.

Because this species is best planned as a group of 6 or more, plan the aquarium around the group rather than a single fish.

Feeding

As an omnivore, Yellowfin Shiner should receive a varied diet rather than one repeated food type.

Natural habitat and origin

This profile currently lists the origin as United States. Treat this as a broad regional note rather than a complete habitat description.

Before adding this fish

Use this checklist before treating the profile as a match for an existing aquarium.

• Plan for an aquarium of 80 L or larger.
• Make sure the aquarium has enough open swimming room for the group.
• Choose other fish with overlapping temperature needs.
• Keep pH stable within the listed range instead of making sudden corrections.
• Avoid aggressive or highly competitive fish.
• Plan for a group of 6 or more.
• Offer a varied diet that matches this species.
