CATDOLL : CATDOLL: I have a small carp, about 5 cm long, and I put some plants on top of the water tank, with the roots in the water and the leaves outside. Will they compete with the fish for oxygen?

hehe

No

Plants' photosynthesis and respiration are carried out through leaves, so they don't compete with fish for oxygen.

Don't worry about that. It's winter now, and the water has enough dissolved oxygen. If the plants don't float for three days, there's no problem. In the spring and summer, you can reduce the density or plant them according to the situation. Plant them if they like them.

Carp is a high oxygen fish, not suitable for hydroponic fish. The roots of plants absorb water and oxygen, so your fish will float (lack of oxygen).

Can the little carp be basked in the sun?

No, the small carp might be sun-dried to death.

Can small carps be exposed to the sun? Small carps can be exposed to the sun, but you need to fill the water with more water, otherwise the temperature will be too high and the fish will not be able to bear it. It will also die.

Definitely not. You can put it in the fish tank under the sun, but you cannot put a fish directly under the sun.

You definitely can't expose it to the sun, as high temperatures can cause death

Fish also need sunlight. All things need photosynthesis to grow.
