Silver Arowana's are great fish to have and one of the most elegant swimmers. I currently have one in my 150 US Gallon tank (and yes, I know a 150 Gallon is too small). Don't put arowana's with any fish that can fit in their mouth, unless you want them eaten. Don't put them with any nippy fish either because they will have a ball nipping at your arowana's long beautiful tail. Lastly, don't put them with any overly agressive fish. I've found in past expiriences that arowana's are very delicate and can't really hold their own against other fish of the same general size.
