Will silver dollar fish get along with guppies?

No, silver dollar fish (Metynnis hypsauchen) generally should not be kept with guppies (Poecilia reticulata). Guppies are small, peaceful fish that prefer warm, well-oxygenated water with plenty of plants for cover. Silver dollar fish, on the other hand, are larger, semi-aggressive fish that require cooler water temperatures and prefer open swimming space. Guppies are typically not compatible with larger, more aggressive fish as they can be easily eaten or intimidated. Additionally, the ideal water conditions for guppies and silver dollar fish differ, making it difficult to keep them together in the same aquarium.
