What Are Bloodworms?
Bloodworms are a group of polychaetes and primarily live on the bottom of marine lakes. They’re the larvae of a midge fly. As indicated by their name, these worms are a rich red coloration. This coloration is shown through their thin translucent body casing. Bloodworms do not consume blood as many believe, instead, they eat a diet of decaying waste, detritus, and sludge.
Bloodworms were first introduced into the aquarium hobby by a fisherman who would use them as bait for marine fish. It led to hobbyists realizing how enticed fish were by these worms and they soon made their way into the aquarium trade.

Goldfish are commonly labeled as being easy to feed. We are familiar with them being described as the ‘pigs of the aquarium’, consuming anything that can fit into their little mouths.

We may want to feed these worms to goldfish, but is it something goldfish require in their diet?

These are examples of necessary goldfish dietary options:
- Bloodworms: these little worms fed life straight into your aquarium are high in protein, as well as fiber for smoother digestion.
