I have a 10g tank established with 3 cory catfish and 3 white skirt tetras. They have been living healthy in the tank for nearly 6 months now. My wife decided to surprise me with 2 tiger barbs tonight to add to it. First of all, I know the tiger barbs should be in a group of at least 4, I can fix that later. The main issue is, she realized on the way home with the fish that there was water leaking from the fish bag. By the time she got home, the bag was deflated and had very little water in it, the rest having leaked out on the car seat. So she just emptied them directly into my tank. This concerns me for 2 reasons. The first, she got them from Walmart and who knows what crud was in the water that went in with the fish, or on the fish themselves. Second, one of the barbs is now swimming completely facing downward, face towards the bottom, tail towards the top. My quarantine tank is not running or cycled so I have no way to remove and quarantine them. Just unsure what I should do at the moment, Any advice will be appreciated.
