Adding fish before the tank is fully ready is one of the most common beginner mistakes.
Allow the aquarium to run without fish for 3–6 weeks and use water testing kits to monitor ammonia and nitrate levels.
Overfeeding your fish can ruin the water quality.
Clear water doesn’t always mean healthy water.
Focus on small, specific goals rather than big, vague resolutions that are hard to follow daily.
Many beginners often underestimate their tank’s capacity.
Choose fish that fit the space and can live together peacefully.
Insufficient filtration, improper heating or poor lighting can negatively affect your fish.
