Diseases and Parasites (more to come later)

This topic is huge. There are so many potential causes for unhealthy guppies and many are difficult to diagnose since guppies can't tell you "it hurts here". The major groups break down to these

Fungus, bacteria, internal parasites, external parasites, water toxins

The most important thing to realize is that once something goes wrong (e.g. pH climbs, nitrates go up too high, guppies exposed to temperature shock) guppies become predisposed to disease and parasites. Rarely will a tank get sick if everything is in balance.
