Cardinal Tetra Fry Care
Caring for the fry does not differ much from caring for the adult fish. However, I want to mention that it is important not to overfeed your fry or end up with a massive amount of dead fry.

How To Feed Cardinal Tetra Fry?
The first food that you should feed your fry is infusoria. It can be challenging to find, but it’s usually in a dry powder. Once mixed with water, the mixture will quickly turn into many tiny microorganisms, which are small enough for your new little fishies to eat.
I recommend feeding them this first before anything else for at least the first week. After that, you can start giving the fry crushed flake food or baby brine shrimp.
How Often Should You Feed Cardinal Tetra Fry?
It would be best if you aimed to feed your fry around four times a day. Again, this will depend on what food you are providing them but as a rule of thumb, four times a day should be good.
What Size Tank Should You Keep Cardinal Tetra Fry In?
Once your fry has reached about an inch in length, you can start to move them into their tank. It’s best to wait until your fry is about three weeks old before you move them into their tank.
The size of the tank can vary, but it should be no smaller than five gallons in volume—the bigger, the better when it comes to cardinal tetra tanks.
How Should Cardinal Tetra Fry Environment Be?
When it comes to the fry, you should keep them in a school of at least five. A bigger tank is better, as they will need plenty of swimming room. The water should be clean and moderate; 68 to 78 degrees Fahrenheit is ideal.
They also require shallow light levels, so either keep the tank out of direct sunlight or use a fragile lighting system. Finally, avoid small tanks, as they can cause stunted growth and deformities.
How To Raise Cardinal Tetra Fry?
Cardinal Tetras are very small in size, and their fry needs the care of with special attention. The main problem you will face when raising them is that they feed on micro food, which you can buy from the pet store. They do not eat flake foods or other types of fish food available for your aquarium fishes. Instead, they nibble on algae and other microorganisms.
Another essential point to remember is that the fry overgrows will need to move them into a larger tank before long. If you do not have a large enough tank, you can either give the fry away to someone who does or sell the fry. Ensure that you do not sell too many to a single buyer when you are selling the fry. Doing this could deplete the population of your aquarium.
