Perfect Tetra Diet

So, tetras are omnivores, which means they need to eat meat AND vegetable matter for their perfect diet.

For meat, tetras usually get that from small invertebrates like shrimp, insects that fall in the tank, bloodworms, and very small fish. You can also feed tetras flakes that contain protein and fat to meet their fat and protein needs.

It’s really easy for them to get an optimal on just flakes and/or pellets.

Remember, they’re omnivores so tetras still need some vegetable matter in their diet. This is where algae enters the picture. In nature, tetras will nibble on random bits of algae that form on rocks and other places like that.

Yes, tetras eat algae, but they will not completely solve your algae problem. They do not need that much algae and the fish themselves are small enough that even if they ate a lot it’s still not much because, well, the fish are pretty small.

Remember, tetras are omnivores, so they don’t really need that many vegetables in their diet. Yes, you can give your tetras algae wafers, but it’s a waste because the tetra will just nibble on them. They will not eat an entire algae wafer as they don’t need to eat that much algae for a healthy diet.
