Stocking ideas for a 5 gallon tank
- 1 male betta + 2 nerite snails
- 8 chili rasboras + 10 cherry shrimp
- 5 Endler’s livebearers (all male, to avoid a population explosion) + shrimp
Small tanks swing in temperature and water quality fast. Use a heater with a thermostat and change 20 to 30% of the water weekly.
Before you add fish
Cycle the tank first, so beneficial bacteria can break down fish waste. Test until ammonia and nitrite read zero and nitrate is rising, which usually takes 4 to 6 weeks. Then add a few fish at a time, with a week or two between groups.
