Fishkeeping Facts and Tips

The biggest killer of tropical fish is overfeeding. Uneaten food decays and pollutes the water, even with adequate filtration. Adult fish should remain unfed one day each week, and almost all commonly available species will be completely fine if unfed during a two week vacation
