My 6-year-old son just got his first fresh water tropical tank. It is 10 gallons. We put in 4 zebra danios, one corydora catfish (speckled??), and one large snail. What would be the best fish to finish off this tank? I've looked around a little and was thinking of adding one beta and one swordtail to get to about 10" of fish. Does that sound reasonable? I know the beta is ok being alone, but what about the swordtail? Does it need to be in a group like the danios? I was thinking of neon tetras, but from what I've read, is that not a good idea? I really want to take him to the pet store with a short list of choices, so that he doesn't get his heart set on one type that won't be compatible. If you were adding fish to this tank, what would you add to complete the fish??
Thanks so much!
