WTF? Live substrate?
I just remembered to post this- About a week ago when I changed my water and did the gravel suction, I found these little worm-like things. I always put the water I suction out in a bucket and then later look at the bucket to find any snails I may have suctioned then pull them out and put them back into the tank. Last week I looked at the bottom of the bucket and saw these short like 1.5 cm long red worms that were as thin as a hair. They were wiggling and stuff. What are these?
