| + | Hybrid fish are often brought up in conversation when it comes to species identification. In order for two fish species to hybridise, they need to be very closely related in the gene pool, even then there's not always a guaranteed cross. Hybrids are not encouraged as they can dilute species and often the offspring are ugly. Many aquarium societies will not except any Hybrid fish to be sold during club meetings or auctions, this is to prevent "contamination" of the genetics of the species. | ||

One other reason that hybrids are discouraged is that most species will not hybridize in nature, Hybrids may also have problems such as fin shape not found in parent fish. Some fish will only hybridize with other closely related fish under certain lighting conditions. | One other reason that hybrids are discouraged is that most species will not hybridize in nature, Hybrids may also have problems such as fin shape not found in parent fish.

They can vary in pattern greatly, and many hybrids are now been selectively bred to create specific strains, such as the Tiger Endler. Many Endlers bought in pet stores are often Guppy crosses, true Endlers have rounded short fins, the crosses will have more angular longer fins. Female Guppy/Endler hybrids will be harder to spot due to the lack of colour compared to males, it's best to rely on the tail shapes to identify them. |

Finding hybrids in the marine fish trade is far more uncommon than freshwater, mainly as only a tiny proportion of marine fish in the trade are captive bred. As the hobby progresses, however, some may appear.
