10 Pet Store Lies Most Fishkeepers Still Believe

Pet stores make fishkeeping look simple, but some of the most common advice beginners hear can lead to unhealthy fish, unstable water, and a lot of wasted money. In this video, we investigate ten misleading lies and claims that pet stores, aquarium packaging, and poorly trained fish store employees still repeat: Lies Covered: 1. Bottled bacteria instantly cycles a new aquarium. 2. Fish only grow to the size of their tank. 3. Filter cartridges must be replaced every month. 4. A common pleco will clean the entire aquarium. 5. Goldfish are perfect for tiny beginner tanks. 6. Running a filter for 24 hours makes a tank safe. 7. Every aquarium automatically needs an algae eater. 8. Bettas are perfectly happy living in bowls. 9. The one-inch-per-gallon rule works for every fish. 10. Aquariums should be completely emptied and scrubbed clean. Some of these claims begin as oversimplified advice. Others make it much easier to sell fish, small tanks, and products meant to fix the problems that follow. Before buying any fish, research its adult size, behavior, and real care requirements. The tiny fish at the store may come with a much bigger future than the price tag suggests. #aquarium
