Hi Fishlore, I had an episode of ich about 3 weeks ago. I treated the tank with temperature and paraguard, and have not seen any white dots for about two weeks now. However, my SAE and GBR are still rubbing against plants, gravel, driftwood and rocks occasionally. However, I haven't seen my neon tetras rubbing on anything since the ich went away. All the fish are eating just fine (great appetite, actually) and show no other signs of disease or distress that I can pick up on. I have been dosing the tank with Paraguard for 3 weeks, with 20% water change every week, and use Prime as my primary water conditioner. I don't have any filter media in my filter since I've heard that charcoal soaks up the medication. I've also been testing my water for the past 3 weeks as well, and the parameters are pretty stable. Here are my readings: Nitrate: 5 Nitrite: 0 Ammonia: 0 GH: 270 Chlorine: 0 Alkalinity: 160 pH: 7.6 Temperature: 83 Any ideas what could be irritating the fish? Or are they just playing/showing off? Is this something I should be worried about? Thanks!
