Dont Want Hybrids - How Can I Avoid It

[Corleone]

Limia and guppy will cross.
Limia and endler will cross.
Limia and Molly will cross.
Molly and guppy will cross.
Molly and Endler will cross.
Guppy and Endler will cross.
Platy and Swordtail will cross.

Platy and Molly won't cross.
Molly and Swordtail won't cross.

One addition: guppy/endlers won't cross with platys or swordtails. Already covered, but for the sake of a complete list.

An fun fact, in my experience, all the species listed here (haven't kept limias, but assume they fall into this, too) will mate with one another. Then again, male livebearers will mate with anything. I have a male platy who absolutely loves the filter intake.

Most of the species on the list are already hybrids to some extent. Most endlers you see in the store aren't pure bred, mollies are mostly crosses from several wild species, and platys and swordtails are crossed extensively to trade color genes, which is why just about any color you can find a platy in, you can find a swordtail to match.

As for Goodieds, they will hybridize with one another. The only species I've seen for sale locally is the black beauty, which is a hybrid.

Adding on to what Corleone said, some goodeids can cross with others but not all can. The problem with goodeids is that they are not all good peaceful members of the community. Although some are fine in a community, many are best kept in a species only tank and even there they may take special care to be successful. Another factor with many goodeids is that they do not do well in the warmth that is usally used for guppies, mollies and platies although their temperature ranges often do cross. A bit cold for a guppy would be warm for many goodeids.

not all goodeids will hybridize with one another.
Goodeids with the same first scientific name can hybridize with one another the black beauty is a cross between skiffia francesae & skiffia multipunctata.
therefore it must be be kept away from any other species of skiffia
to be on the safe side it is best to keep them in a species tank.

All goodeids will be fine between 68f – 74 f many goodeids will suffer and even die when kept above 76f . however ther are a small number of goodeids that do wall at a higher temp- .

Although many goodeids do well between 68 and 74, it is another much too broad brush. There are some that do 75 to 85 while most go down to at least 68 and few go above 78.

Sorry OldMan, you seem to have repeated what Fish48 has said, although in what you have said that ''many' goodeids do well...' you seem to be suggesting that some goodeids will not do well at these temperatures. Would you mind clarifying what you are saying as it appears to be a little misleading.

In my experience, all Goodeids, without exception, will do well between 68 and 74 degrees Fahrenheit (as Fish48 has said), some, such as Ataeniobus toweri will do well at higher temperatures, but most will not. Most Goodeids will do OK at lower temperatures than 68, infact, I bought my Chapalichthys pardalis, Allodontichthys zonistus, Ameca splendens, Xenotaenia resolenae and Xenotoca eiseni and melanosoma in from the garden a few weeks ago when the temperature at night and early in the morning started to get below 5 degrees Celsius. They were doing fine at that temperature, but I am pretty sure they would not have survived the snow we have just had; some species, such as Zoogeneticus quitzeoenis do not do well at lower temperatures.

Sorry Duncan, I had just finished reading through the needs of each of the individual goodeids to see what I could add to my eisenii, xenotaenias and amecas and was looking at the temperature ranges because I also use outdoor pond situations. I don't recall which ones that I came to the conclusion that I couldn't keep that way but there were a few. I have no experience with them but there were whole groups that listed 75 to 85 as the needed temperature range. Most, as you have said, had ranges that went quite a bit lower than the typical aquarium. There were also a few, not many, that I decided needed water cooler than I could easily provide in the summer because the top of the suggested range was so low. I have no experience with these particular fish, that is why I was doing the research. It is entirely possible that you are right and they could go lower but that is what I was finding.

That is no problem, I thought that your post had said something slightly different than you had meant to say.

Why don't you check out the website www.goodeiden.de, that has alot of good advice.

My opinion, for what it is worth, is that ALL Goodeids do fine at the range 68-74, I have never come across one that doesn't but I have found that Zoogeneticus quitzeoensis do not do very well with a sustained temperature below 60. That said, as far as I am concerned, Fish48 (Gary) is THE MAN when it comes to breeding and keeping Goodeids.
