I have seen afew worms crawling around the tank. Some of them are small (1/2 in. long) and white, some are black and red and look like centipedes (about 1 in.long), and some look like teeny night-crawlers poking out of the rock and feeling around? What arethese? Are they bad? If they are bad, what should I do about it? Thanx in advance
