What does a female glofish look like?

Glofish are genetically modified zebra danios, and as such, there is no real difference in appearance between male and female glofish. They come in a variety of bright, fluorescent colors, including red, orange, yellow, green, and purple. Their bodies are typically long and slender, with a forked tail and small fins. The females may be slightly larger than the males, but this is not always the case.
