Help! I cleaned my betta's tank about 3 hours ago, and I accidentally forgot to put conditioner in! I just realized and fixed my mistake, but my usually spunky and active betta is just floating near the top of his tank. He's not dead (I checked), but did those few hours in the new water hurt him? I just want to be prepared if it ends up that there's no chance of him pulling through this, but I'm hoping this is not the case. Any ideas as to why he's acting strangley?
