Looking for a easier way to get some of your tetras to breed with little effort. I use blackwater extract to help soften and enhance the water so that it kicks my fish into the breeding mood. The only down fall of course is the tinting of the water to a brown color but it can actually help bring the color out in some fish. Tetra makes this product and for a great price also making it affordable for almost any hobbyist to extreme breeder. Also another great benefit to using a blackwater extract is Contains trace elements, vitamins, and extract of peat. Hobbyist love this product and so will you if you love breeding or creating a more natural habitat for your fish.
