indeed, well said, perception is reality. i understand the two points above, but i agree with three posts above, i frown upon them and do not encourage such sales. this was a natural species that has been altered. such creations can drastically effect ecosystems if released. this isn't really relevant but it's an example of how ecosystems can be effected and if you don't know about this yet you will in the coming year or so - the lionfish is taking over the US east coast. in some places a lionfish has been found in every square meter! although i admit i can't see glofish becoming an epidemic of such proportion.
getting back on topic, why create new species (which in my opinion are hideous - a fish full of highlighter ink!) when we haven't even discovered and described 90%+ of the natural species out in our world? i just prefer natural fish, fish you would find in the wild and not in a lab. Danio rerio, for example, can be very beautiful.

but, just my opinion. don't mean to stray from the topic and start a war, just wanted to share my thoughts.
staying on topic, i imagine care for glofish is the same as that of Danio rerio (zebra danios). doesn't matter what gravel you choose, they dont need it, but most aquarists prefer it for aesthetic fulfillments. make sure it wont alter the pH though. the fish won't grow larger than an inch and a half or so. theyll probably eat almost anything you throw in there - flake, worms, daphnia, brine shrimp. don't know anything about the snail, but i imagine small danios can't hurt it.
