Let’s get to know more about these worms below.

What are detritus worms?

If you’re seeing thin, white worms wriggling in your turtle tank water column, or substrate, they’re most likely the detritus worms.

These worms belong to the same family as earthworms and leeches. There are thousands of detritus worms in turtle tanks that come in various colors (not just white!), including brown, black, red, etc.

Tube worms, tubifex worms, and those red or brown worms you may have encountered in your tank are all detritus worms and mean no harm to your pets!

What are detritus worms

A typical detritus worm grows up to an inch long. The adult worms are excellent hitchhikers and can easily find their way into your tank by attaching to the driftwoods, sand, substrates, or even fish.

Note that these worms like to confine themselves below a substrate or in the filter in your water tank. However, they’ll climb up to the tank surface as their numbers swell and there’s a scarcity of oxygen and supplies.

Thus, if you’re seeing these worms wriggling around in your tank, it means their numbers have rapidly outgrown, forcing them to come out.

So, what causes their rapid growth inside your turtle aquarium? Other than hitchhiking, the most likely reason for the presence of these worms in your tank is overfed tanks. The worms like feeding on leftovers and wastes produced by tank inhabitants.

Remember, turtles are messy eaters and always leave plenty of food particles inside the water after every feeding session.
