First tyranid painted, part of hivefleet... Can't think of a name. Thoughts?

Had some termagants and decided to paint one for practice for my combat patrol magazine. But I got some questions, 1: I'm not too sure about the bugmans glow, and other color recommendations? 2: How do you find all these cool names for your hombrew hivefleets? Is there like a name generator or something? Feel free to answer whatever you want, but be respectful please. Thanks.
