Claims

  • *[Paraphrased derived summary — non-Open-Access source.]* Some fish species grow too large for home aquaria — examples include red-tail, shovelnose and pangasius catfish, giant gourami and pacu.
  • *[Paraphrased derived summary — non-Open-Access source.]* Before adding fish, the tank must be cycled by establishing beneficial bacteria (using a starter product) that keep the water safe.
  • *[Paraphrased derived summary — non-Open-Access source.]* Healthy fish have smooth scales with no sign of injury or fungal growth.
  • *[Paraphrased derived summary — non-Open-Access source.]* Breeding for extreme physical traits harms welfare, so such fish are discouraged.
