Danios like water movement. Make sure there is water movement from the water filter.
Your test kit can also measure water pH (acidity). Danios do best in water pH from 6. 5-7. 2.
Only use freshwater aquarium salt, not ordinary salt. Do not add salt more than once between water changes. Salt does not leave the tank, so adding more can cause a lethal overdose.
If you have a large tank, introduce the new fish two or three at a time. Wait a week or two between introducing groups. This minimizes the disruption to your tank’s chemistry, as well as stress on the fish.

Although zebra danios are peaceful, they are active swimmers. Some fish species may prefer a calmer environment. Danios may be “fin-nippers”, especially when they are not schooled with other fish.

Each danio should only need a couple bites of food each feeding, 2–3 times per week, but can be fed each day if the other fish in the aquarium need feeding each day. Overfeeding can cause bloating as well as harmful chemical build-up in your water. Only feed the fish as much food as they can eat in 3 minutes. This is a general rule for all freshwater aquarium fish.
