They were in a donation tank at petco in with some gold fish, cichlids, and a huge gourami. While I watched, the gourami ate one of them! So I bought them and brought them home, but I haven't done much research on them yet. What do I feed them? They're not much bigger than fry, and they look relatively healthy, if a bit thin (I suspect they haven't been able to compete with the bigger fish). Also, since they were in a donation/quarantine tank, should I treat them with some medicine just in case? I have them acclimating in a cycled 5 gallon tank at the moment. Edit: I got a decent picture of two of them, how do they look?
