• pH Levels: Aim for slightly acidic to neutral water conditions, ideally between 6.0 to 7.5.
• Water Hardness: Keep water hardness in the soft to medium range, around 5 to 15 dGH, replicating their native Amazonian habitat.

Tank Size and Setup:

• Exodon paradoxus requires a spacious tank of at least 75 gallons to accommodate their active nature.
• Provide a well-decorated environment with ample hiding spots, rocks, and driftwood to mimic their natural habitat and reduce aggression.

Tank Mates:
