A little while ago I found these little white worms wriggling all around in my tank. I had them before with fish, was told they were "nematodes" and that the only way to kill them was by bleaching. My fish ended up dying and I'm sure these critters didn't help.
Now, these things have come up for the third time in my turtle tank. I bleached everything the first two times and thought the coast was clear, but now they're back. My question is, are they harmful to the turtle? Could they be coming from the turtle? Or are they just gross to look at? They're not very big, less than an inch in length. They're white and wriggle around on the sides of the tank and kind of swim through the water.
The water is kept from 76-80 degrees (depending on how hot the house gets) he has his lights on for 12 hours a day, and since they second time I found these things (after bleaching and all) I've been feeding my turtle outside the tank. However, there is some waste in the tank from after he eats.
Thanks for any advice
