Best Locations for an Aquarium Fish Tank at Home
Placement plays a major role in the health of your fish and the overall appearance of the tank.
Do:
- Place near a power outlet
- Ensure it’s on a flat, stable surface
- Keep away from direct sunlight (prevents algae growth)
- Choose a visible spot where you can enjoy it daily
Don’t:
- Place next to windows or heaters
- Put it in high-traffic areas where it can get bumped
- Install on unstable or unlevel furniture
What Size Aquarium Should You Get?
Size affects everything: how many fish you can keep, how stable the water stays, and how easy the tank is to maintain.
Tank Size | Ideal For | Notes |
---|---|---|
5–10 gallons | Beginners, Betta tanks | Easy to manage, good for one fish |
20–30 gallons | Community tanks | More stable, allows small groups of fish |
40+ gallons | Advanced setups | Requires more space and support |
75+ gallons | Saltwater or showpiece tanks | Ideal for experienced aquarists |
Tip: Bigger is often better. Larger tanks are easier to maintain because they offer more stable conditions.

Setting Up Your Aquarium Fish Tank for Home
Setting up an aquarium is exciting but requires patience. Follow these steps to start right:
Step 1: Rinse Everything
Always rinse your gravel, decorations, and tank with plain water (no soap).
Step 2: Add Substrate and Decorations
Layer your gravel first, then add decorations like rocks, driftwood, and artificial or live plants.
Step 3: Install Equipment
Position your filter, heater, and thermometer, but don’t plug them in yet.
Step 4: Fill with Water
Use room-temperature water. Add a dechlorinator before turning on your equipment.
Step 5: Cycle the Tank
Let the tank run for at least 1-2 weeks to establish beneficial bacteria before adding fish.
