I think they're really cool fish, and if you had one for a child it's be a wonderful way to introduce them to loving aquatic life, but there's a lot that's left to be desired.
I feel like while Danios and Tetras should have schools, and at least a minimum 10 gallons, they're trying to sell glofish habitats that are, say, 5 gallons and cheesy neon things, that don't make those kinds of fish happy. They're making them out to be a completely different species, but they're not.
Then again, if they made a glofish catfish, I'd definitely be head-over heels. But for right now, I'm not too impressed.
