It's DROPSY or a condition that is caused by unfavorable water, your fish will die if you don't change 25% of your water and cleanup your aquarium and filter.
Tiger Barbs are not nocturnal. They are only active in the daytime (or if you have a tank light on). When it is dark, they "sleep" which is what you are talking about. Its not a bad thing don't worry. Also, they are easier to catch because they are very slow for the 2 minutes after they wake up.
Tiger Barbs are a more sensitive fish. They stress out very easily with water quality issues. They also can be "nippy." Generally, however, if you get them in a group of five or more, they will play together instead of picking on other fish. A 29 gallon tank would be fine for tiger barbs. Generally, your tank should hold one inch of tropical fish per gallon (29 inches of fish for your tank). The tiger barbs will grow up to about 3 inches each, taking up about 15 inches if you get 5. You would then have 14 inches left over to get more fish. Just don't forget this rule when deciding on whether or not to purchase these fish.
