⚠️ Monster Fish Care Notes:

Redtail Catfish are not community fish and should only be kept with:

• Other large, durable fish (Datnoids, Peacock Bass, Giant Gouramis)

• Compatible bottom dwellers like Ripsaw Catfish, TSN, or large Bichirs

• No small tank mates – anything that fits in their mouth will be eaten

These fish grow very rapidly and require large, wide tanks or ponds with smooth décor, excellent mechanical filtration, and regular water changes. Redtails are also known to recognize their keepers, becoming active during feeding and tank interaction.
