My daughter-in-law has had guppies for quite a while. She got frustrated because they kept dying and decided to give the tank and its 2 remaining male guppies to me. I told her I could help her keep them alive, but she isn't interested in continuing to keep fish. It is a 5 gallon, so won't hold any more fish, but I am looking forward to taking care of the 2 little ones and hopefully keeping them alive. I may even add an african dwarf frog later when I am sure all is well.
