Appearance and identification
A trade name alone cannot identify a specimen.
Aquarium environment
A large planted aquarium suits it; water quality and feeding access remain essential.
Diet and feeding
Offer mainly plant-based foods and appropriate sinking foods, with occasional animal foods. Natural algae alone are not a feeding plan.
Same-species behaviour
Use spacious planted housing with non-aggressive companions and regular water changes.
