Simple Fish Care Tips for Low-Maintenance Tanks
Even low-maintenance aquariums need some care. Follow these simple tips to keep your aquatic pets happy and healthy.
Perform Weekly Water Changes
Change about 10–20% of the water weekly. It keeps nitrate levels low and your fish vibrant.
Monitor Water Quality
Use test strips to check for ammonia, nitrites, and pH. Most fish thrive in neutral pH (6.5–7.5).
Avoid Overfeeding
Feed your fish only what they can eat in 2–3 minutes, once or twice a day. Overfeeding causes water pollution.
Keep the Tank Clean
Clean the glass with a magnetic scraper and vacuum the substrate every 1–2 weeks.
Use a Reliable Filter
A low-maintenance fish tank still needs good filtration. Choose a filter that suits your tank size and clean it monthly.
Provide Hiding Spots
Decorations, plants, and caves reduce stress in fish and make them feel secure.
