Are Bloodworms Good for Mollies?

Yes. Since Mollies are omnivores, they can eat pretty much anything without any problems, and bloodworms are entirely safe for them and actually pretty good for their health.

Giving your Mollies a small serving of bloodworms is like pressing the snooze button on their hunger. It wakes them up like nothing else. Plus, bloodworms are an excellent source of protein, vitamins, and minerals your Mollies need to stay healthy.

The only downside is that bloodworms are also high in fatty acids, which is not great for adult Mollies who need a lower-fat diet. So, keep the bloodworms to a minimum.

But otherwise, there is nothing wrong with offering your Mollies some bloodworms as a tasty and nutritious treat.

Just make sure to keep their diet balanced with other foods like fish flakes, algae pellets, and fresh and frozen veggies.

Freeze Dried Bloodworms OR Frozen Bloodworms?

However, they require some soaking before feeding, are very lightweight, and do not sink in the water.

On the other hand, frozen bloodworms are usually of higher quality than freeze-dried ones and do not require any soaking. They are also heavier, so they sink to the bottom of the tank and are easier for your Mollies to eat. 

Frozen bloodworms can be a bit more expensive, but many Molly owners find them worth the extra cost. Ultimately, the choice between freeze-dried and frozen bloodworms comes down to personal preference and budget.
