Wavey Kuhlii Loach??

[abe]

My mom has been watching over my fish for about 3 weeks now, so I haven't gotten to see my fishes too much lately. I moved in w/ my boyfriend to help out as he recovers (he had been in the hospital for about 6 weeks, not sure if anyone remembers my post about that ), & sadly my fish are the last to move in. Anyway, I was watching them the other day while I was at my mum's, and one of my kuhlii loach's was wavey looking. Like his spine was curved, only over & over again.

Other than that, he seems healthy & happy, just a little curvier. Any ideas? Should I do anything?

I'm having a little difficulty here. They often rest bent in all kinds of shapes. What you mean is more rigid?

It's like he's stuck in this wavey pattern, I thought he was just laying that way but he swims around & he's still crooked looking. I'll take a picture the next time I'm over there, it's kinda freaky looking
