Fish Checklist: Setting Up a Healthy Aquarium

Fishkeeping is a rewarding hobby that brings beauty, peace, and life into your home — but it requires the right preparation.
At PetsConnected.com, we want every fish to live in a well-maintained, healthy environment.

Here’s your essential checklist:

🏠 Preparing Your Aquarium

✅ Choose an appropriately sized tank based on the type and number of fish you plan to keep (bigger is always better)
✅ Set up a sturdy stand and level surface for the tank
✅ Install a reliable filter suitable for the tank size
✅ Fit a heater if keeping tropical fish (and a thermometer to monitor temperature)
✅ Use an aquarium-safe lid to prevent fish from jumping out

🌱 Substrate and Decoration

✅ Select safe substrate (gravel, sand, or species-specific)
✅ Add plants (live or artificial) for shelter and aesthetics
✅ Provide caves, driftwood, or ornaments for hiding spaces and natural behaviour
✅ Rinse all decorations thoroughly before placing them into the tank

💧 Water Quality

✅ Use dechlorinated tap water or treated bottled water
✅ Set up a water testing kit to monitor pH, ammonia, nitrites, and nitrates
✅ Cycle the tank properly before adding fish (this can take several weeks)
✅ Perform regular partial water changes (typically 20–30% weekly)

Good water quality is critical for healthy fish.

🐠 Choosing the Right Fish

✅ Research species carefully — not all fish are compatible with each other
✅ Avoid overcrowding; know the adult size and social needs of each species
✅ Start with hardy beginner fish if you are new to fishkeeping
✅ Buy fish from reputable, ethical sellers who provide healthy, properly quarantined animals

🍽️ Feeding

✅ Use species-appropriate food (flakes, pellets, frozen foods, etc.)
✅ Feed small amounts once or twice daily — avoid overfeeding, which pollutes the tank

🩺 Health and Care

✅ Watch for signs of stress or illness (clamped fins, unusual swimming, loss of appetite)
✅ Set up a separate quarantine tank for new fish if possible
✅ Plan regular maintenance for filters, lights, and equipment

💷 Financial Responsibility

✅ Budget for ongoing costs like electricity, water treatments, food, equipment repairs, and potential vet care (especially for rare species)

Fishkeeping is about creating a miniature, thriving ecosystem — and the rewards are spectacular.
