ok i was looking at my H. maculata when I noticed a small speck running across the glass. I got a magnifying glass and looked closer and seen quite a few more. I immediatly took out the T' and dumped the substrate then bleached the tank. then I ran water in it and let it overflow for about 5 min. its airing out now. my question is how long before I put new substrate in, and should I be worried about them being on my T' or even worse could they have moved from 1 tank to anouther.
