Golden Trunkhead Catfish ( Cryptarius truncatus ) 2-3"

“gold or golden trunkhead catfish” — the correct scientific name appears to be Cryptarius truncatus (sometimes written “trunk-head catfish” or “trunkhead catfish”

Key facts

• Scientific name: Cryptarius truncatus. Sometimes sold under the common name Gold / Golden Trunkhead Catfish.  
• It’s offered in the aquarium trade. For example, one listing: “Gold Trunkhead Catfish (Cryptarius truncatus) – Upscale Aquatics”  
• Care / size / habitat details are limited in freely available sources, so caution is advised when considering keeping one.

What you should know before keeping one

• Tank size & environment: Since many catfish species grow fairly large and may need good water flow, hiding places, robust filtration, and stable water parameters, any prospective keeper should ensure a suitably sized tank and appropriate setup (though I couldn’t locate a well-documented “minimum tank size” in the sources).
• Behavior & compatibility: Because detailed behavior data are scarce, one should assume it might be territorial or require care with tankmates that won’t stress it or be prey.
• Origin & status: It appears in the aquarium trade, but I did not find detailed conservation status or wild-population data for this species in the sources I checked.
• Authenticity & naming: As with many aquarium fishes, common names can be misleading, and the “gold” in its name may refer to a color/variant in trade rather than a wild phenotype. Always check verified scientific name when purchasing.

My recommendation

If you are considering this species for an aquarium:

• Verify the exact size of the specimen being sold (and expected adult size) so you can size the tank appropriately.
• Ask the seller about water parameter requirements (temperature, pH, hardness), diet, and temperament.
• Provide plenty of hiding spots / structures (rocks, driftwood) and ensure good water quality & flow.
• Make sure tankmates are chosen with care (avoid very small fish that may be prey, or very aggressive fish that might bully the trunkhead catfish).
• Be aware this might be a less commonly kept species, so hobbyist experience may be more limited and disease/health advice less abundant.
