About Hybrids

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.

Hybrids are usually associated with great controversy especially when the species is now extinct in the wild.

An interesting observation, especially with Catfish hybrids, is the growth of these fish is twice as fast as their purebred relatives, this must be taken into account if you are considering keeping a hybrid! They may also grow larger than either of their purebred parents.

Below we have compiled a list of true hybrid fish and how they came about.

Livebearers

Not all livebearers can hybridise, a Guppy and a Platy for example, cannot cross. These, however, can:

  • Guppy x Endler - They will have the elongated fins of the Guppy, but the orange/black distinctive spots of the Endler, they will also be smaller than a Guppy. 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.
  • Platy x Swordtail - Closely related, won't create fish that look much more different than a Platy.
  • Platy x Platy - There are several Platy species, store-bought Platys are usually hybrids already.
  • Molly x Molly - (or Poecilia sphenops), as above with Platys.
  • Molly x Guppy - Called a "Muppy" or "Golly". This does happen, but the fry are sometimes very weak and do not live long. Even if they are stronger they are usually nondescript in coloration and fins and people rarely persist with them.

Cichlids

Not all Cichlids can hybridise either, and crosses are often unsightly and undesirable, the exception being the Blood Parrot Cichlid and the Flowerhorn. It is NOT encouraged to breed these hybrids and put them into the pet trade, it only dilutes bloodlines.

American Cichlids

Male Flowerhorn
Blood Parrot Cichlid

It must be noted that many of these crosses are highly aggressive fish and are best kept in species tanks or with equally mean-tempered robust tank mates. The only real exception is the Blood Parrot, but it can still pack an attitude if it wants to!

African Cichlids

You need to be really careful when buying African Cichlids, specifically Mbunas, from pet stores as many on the market are hybrids, if you want genuine purebreds it's best to go to fellow breeders or at least enquire further about their history. Never buy African Cichlids from a tank labelled "mixed Cichlids", you don't know what you're going to end up with.

Catfish

Catfish hybrids are far less common than Cichlid or Livebearer but not unheard of. Common Catfish such as Plecos and Corydoras are very unlikely to hybridise however. Here are some of the known hybrids:

Marine Hybrids

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. The following have been seen on sale.
