They reproduce extremely fast and almost impossible to get rid of them. Last year I found a couple crawling in my tank and thought "oh so cute" so I left them there. The next thing I know, they were hundreds of them on the substrate and a whole lot more under it. At feeding times, the substrate were literally moving. It was creepy. I put dwarf puffers in there to eat them, but they couldn't do the job. The shells were too hard for them. I even try putting huge puffers in there but no help there either. So ... I ended up emptying the whole tank, changed the substrate, and scrubbed every inch of the bogged wood to get rid of their eggs.
