Quick answer: Redtail catfish is a variety of catfish. Everything on this page is catfish-level guidance — we do not invent variety-specific numbers.
The care below is catfish-level guidance from our species hub, sourced to Merck Veterinary Manual — Aquarium and Pond Fish and RSPCA — Fish care. It applies to Redtail catfish exactly as it applies to every other catfish variety. We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.
Sinking wafers, frozen foods, and for corys, a little sinking pellet; they are omnivorous scavengers but still need fed food, not just leftovers. Redtails eat large meaty meals and will eat tank mates. Never use sharp gravel — it destroys the sensory barbels catfish feed with, leading to starvation and infection.
The single biggest catfish mistake is buying a cute juvenile of a species that becomes enormous (redtail, pangasius, giant gourami-adjacent cats). These fish outgrow homes and are abandoned. If you cannot house a 3–4 ft fish for 20 years, choose corydoras or a confirmed small species and confirm adult size in writing.
