🐟 New fish often carry parasites, bacteria, or fungal infections that may not be visible right away.

🦠 A separate quarantine tank (QT) / hospice tank (HT) allows you to observe, treat, and stabilize fish before adding them to the main tank.

• ✅ Tank Size: 10–20 gallons is ideal for most fish; larger species may need more space.
• ✅ Bare-Bottom Tank: Easier to clean and monitor waste buildup.
• ✅ Vacuum: Daily removal of waste and parasites (gravel vac works).
• ✅ Filter: Use a sponge filter or cycled media (no carbon if medicating).
• ✅ Heater: Keep temperature stable for the species.
• ✅ Aeration: Airstone or sponge filter for oxygen exchange.
• ✅ Hiding Places: PVC pipes or plastic plants to reduce stress.
• ✅ Light: Dim blue light 24/7 can reduce stress; many diseases thrive under bright light.
• ✅ Lid/Cover: Prevents jumping due to stress.

• ✅ Observe for 2–4 weeks – Watch for scratching, weight loss, or odd swimming.
• ✅ Feed a nutritious diet – High-quality food boosts immune function.
• ✅ Test water regularly – Keep ammonia & nitrites at 0 ppm.
• ✅ Medications (Optional):
  • 🦠 Preventative Antiparasitic: Praziquantel (PraziPro) or Metroplex.
  • 💊 Broad-Spectrum Antibiotic: Kanaplex or Furan-2 if infection is suspected.
  • 🍄 Antifungal (if needed): Methylene Blue for stressed fish.

• ✅ If no symptoms after 3–4 weeks, the fish is safe to introduce.
• ✅ If treated, extend QT another 2–4 weeks to confirm recovery.
• ✅ Proper acclimation reduces stress and prevents shock.

• ❌ Skipping Quarantine – One sick fish can wipe out an entire tank.
• ❌ Sharing Equipment – Always disinfect nets, siphons, and tools.
• ❌ Using Carbon While Medicating – Carbon removes medication.
• ❌ Medicating Without Diagnosis – Identify the disease first.
