They're fantastic! They look faded out in store, but once settled in a tank they look really sharp. I like their more outgoing personalities too, for a smaller tetra they're not shy and don't care to hide when I'm around. They come to the glass hoping I have food which is nice. Most of my small species of tetras all dart away when the tank is approached, so it's neat having a tetra that will come and see to see if you have something for them lol and they spar often but aren't aggressive. I've had bad experience with neon tetras, I'll never own the little devils again lol I steer clear of the whole Paracheirodon genus because of them (no cardinals, green neons, or neons for me lol)I hope this means a lot of members think about keeping glowlight tetras. They're often overlooked beauties, and @CassCats caught them looking very good indeed. There were a lot of very attractive little fish in this contest, all there for us to explore.
