Overfeeding is the most common aquarium mistake I see, and it’s often the hidden cause of ammonia spikes, cloudy water, and biofilm. In this short video, I break down a real 20-gallon tank case and show how simple feeding changes stabilized the entire aquarium.

A struggling 10-gallon aquarium doesn’t mean failure — it usually means the system needs support. In this real-world example, I walk through how a small freshwater tank was stabilized, upgraded, and set up for long-term success using calm, practical aquarium care methods that work in real homes.

Our last night in Prague was one of those evenings where you don’t really have a plan, you just walk, wander, and try to take it all in before it’s over.

Life in the goldfish tank has been so sweet lately. Cocoa, my little rescued Black Moor, has been spending lots of time side by side with Topaz, my bright orange Fantail.
