Mrazisharium

A small journal about planted nano tanks and freshwater shrimp.

Cycling a 20-litre tank without fish

Add a pinch of shrimp food every other day and test for ammonia and nitrite weekly. When both read zero for a week straight, the filter bacteria are ready and the first shrimp can move in.

Mosses that forgive beginners

Java moss and Christmas moss grow on almost anything, need no extra CO2 and give baby shrimp a place to graze. Tie them to a stone with cotton thread; it rots away once the moss attaches.

Why stable water beats perfect water

Shrimp cope with slightly hard water far better than with sudden changes. Change ten percent weekly, drip-acclimate new animals for an hour and keep the temperature steady.
