Since my goldfish died becuase of my 3 days without power i have decided to turn the 30 gallon into tropical and then when i get a bigger tank then the 10 gallon i will use the bigger tank for goldfish! I had 2 female guppies, but one died, and 1 male guppy and 1 male baby guppy and the one female left and the baby male and the male were interacting and the female gave birth yesterday while i was on the computer! I did not get to watch becuase everytime i went over there she stopped! I caught 5 of the babies and there is still one in there becuase i want to keep fish that i have raised! So so far it is working! I will post pics later!
