how did you make the fireball?
maybe try making a sphere, add the fire fx to it, and either hide the sphere or colour it
see how that turns out...unless that's what you did.. in which case play with the fire fx settings again 
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Objective C, C#, Java, MEL. Python, C++, XML, JavaScript, XSLT, HTML, SQL, CSS, FXScript, Clips, SOAR, ActionScript, OpenGL, DirectX
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
