Turns out all the guppies aren't male after all. Yesterday morning looked in the tank and there were a few fry. Managed to get some really good pictures I will post tomorrow thanks to my awesome camera. I am just letting nature take it's course. There are at least 4 fry. Next month I may seperate some and see if we can get some to make it to adults. It's only a 15 gallon tank and we have 4 guppies and 1 oto and now the 4 fry. I am planning on getting 2 more otos as was suggested by others in the near future. Guess I am going to hold off on buying any fish and this tnak will end up being a mainly guppy tank. The fry seem to be eating the flakes that I crushed and they are so fast. Oh well. Now I just need to figure out what sex the adults are, I have no idea which fish was the mother.
