5 Deadly Beginner Mistakes (Learn From My Fail!)

Overfeeding: Fish stomachs = pea-sized. Feed 2x daily, tiny portions.
Skipping cycling: Use API Quick Start + test kit. Wait 2 weeks minimum.
Mixing enemies: Bettas + guppies = fin-nipping drama.
Tap water toxins: Always use dechlorinator.
Impulse buys: Research before buying “cute” fish!
