Can you put a betta fish with calla lily plant in vase?

Calla lilies are toxic to fish. The plant's sap contains a chemical called calcium oxalate, which can irritate a betta's gills and cause respiratory problems. In some cases, it can even be fatal.

In addition, calla lilies require a lot of oxygen to survive. This means that they will compete with the betta fish for oxygen in the water, which can lead to stress and health problems for the fish.

For these reasons, it is best to avoid putting a betta fish with a calla lily plant in a vase.
