Diamond tetra fish is a mesmerizing fish to look at.

Keeping in mind that the diamond tetra is a peace-loving fish species, it must be noted that they'll only show aggressive behavior or get mildly dangerous when they sense a threat.

They are usually bought because they are calm, however, they might turn slightly aggressive if they sense danger or even under circumstances when they are unable to adapt to their tankmates, the tank size, and the hardness and acidic nature of the water of the tank.

A pair, or often a community, of diamond tetras, is left to spawn in an aquarium well covered with leafy plants, preferably java moss.

Soft acidic water with a pH range between 5.5-6.5 is ideal.

The tetra fish are well-fed with proper nutritious live food before spawning. The preferred temperature during the breeding period should be around 84 f ( 28 C ).

The hardiest tetras are the neon tetras, generally silver, red, and blue. They are best suited for community aquariums as they are easy to handle.

Black skirt tetras, bloodfin tetras, Glowlight tetras, Serpae tetras, and X-ray tetras are the hardiest tetra fish. Although most fish change their gender during their lifespan, a tetra usually doesn't do so. According to researchers, a neon tetra's sex cannot be determined until it has reached four months of age.
