I'm very new with having a fish tank. I was given a 30 Gallon tank with everything that is needed to run a fresh water tank. I went to the pet store and got two Dalmation Fish. One male and one female. I was told that the female was pregnate and would give live birth. I thought that would be really neat for my kids to learn about. Today when I was feeding the fish I noticed that the female didn't look pregnate anymore and then saw a bunch of eggs around the top of the tank. How long will it take for them hatch? Do I need to do anything special for the eggs to take care of them?*GOLDFISH*
