silver arowana spine problems?

[Swimfan]

Hello,

I have had my silver arowana for about 8 months in my 240 gallon tank. About 4 days ago, I noticed his spine was curved and his tail is bent upwards. It hasn't ate shrimp or pellets either. I read some articles about fish TB and freaked myself out. So can anyone tell me what they think may be going on?

Check for stray electrical current.

It doesn't seem like there was... no signs right now. Were you thinking a heater short out? I have two newer fluvals and the plastic piecing around them have no indication. I have six other fish in there and they are all fine. Any other suggestions?

Hope this helps.

Probably panicked and charged full speed into the glass.
