I'm guessing I have some free swimming ick in my 5 gallon tank, but I'm not sure. I can't seem to find any description or pictures of what this stage would look like. I even read d3sc3n7's article on ich/ick many times over and couldn't find my answer (GREAT article btw). Has anyone seen this stage before? When I woke up this morning, and turned on the lights on the 5 gallon, I saw very, very small bubbles of 02 rising from my plants - and I thought, this was cool. But then I saw some of the things I thought were bubbles started switching direction and "swimming" downward. I don't know how else to describe it other than, they seemed to move around in the same manner baby brine shrimp would. These things are about the same size of bbs as well. The only new fish I've gotten are the dwarf gourami pair - but they went into the 10 gallon, and nothing seems to be going on there. So I figured maybe they came in with the new plants I had just bought. I checked in the 15 gallon, which has some of those plants too, and I saw nothing. (If anything, the only things I saw on the plants in the 5 gallon were snail eggs and what I'm going to assume are cory eggs - more on that later). Maybe it's possible they've just been in their dormant stage for a while? I stared my fish down for a couple of minutes, and didn't find any signs of ich on them, or anything else. I did find one of my pygmies dead this morning though . When I get home, I'll be dropping in 7.5 watt heater in there to try to bring up the temp to the mid 80s, and I'll also be doing a water change. I wanted to use salt treatment, but with my cories in there, I don't think I should... unless, maybe I use half-dose? Would Coppersafe cause any harm to my cories? Can anyone think of anything else those little swimming things could be?
