I just got 3 tiger barbs and 2 albino tiger barbs yesterday, and a few of them seem to be doing a headstand. They are swimming head down in place in the water. I googled this and some people said it was normal, and some said it wasn't. What could this be? Is it normal?
This will sound kind of odd, but if they are not dead after 24 hours of it, my guess is that they are fine, and you just have some silly fish. Just make sure to watch the water parameters and make sure the water is clean. Sometimes fish just have odd quirks!
I have a single tiger barb in my 20 long and my girlfriend and had noticed he was doing the same thing so I watched him for a couple days and he's fine. And this was like 2 weeks ago that she noticed. I wouldn't worry too much
I have 7 tiger barbs, 9 albino tiger barbs, and 6 platinum blue barbs...all three variety do the same thing all the time when in a resting mood. It almost seems like they need to be almost on their heads to be comfortable!
