First off, i got this pic from Al, sorry to jack your pic but it is exactly what I needed, if you want me to take it down let me know thanks.
Anyway, yesterday I started noticing several of these at the bottome of the tank, there were quite a few of them with various size ranging from 3/8" of an inch to 3". Are they harmful? if so how can i remove them as they tend to hide in rocks and under the sand.
