: Flowerhorns are extremely territorial and are generally best kept alone in their own tank. 5. Where to Buy Look for reputable breeders who provide:

: Photos of the parent fish (sire) to gauge potential.

: A minimum of 55–75 gallons is required for an adult, though 90–125 gallons is highly recommended to maintain stable water quality.

: Ensure they are not "clamped" (held tight to the body), which can signal stress or parasites.

: Sand or large tile is best; avoid small gravel they might swallow. Water Conditions : Temperature : 75°F–85°F. pH : 6.0–8.0.

: Look for a thick, muscular build with a slightly rounded belly—avoid fish that appear "emaciated" or "bloated".

: Seek vibrant, well-defined reds, oranges, or yellows. "Pearling" (metallic lines) should ideally extend onto the head and gill plates, as this signals full-body development in high-end strains like Kamfa (KFA) .
