Guppy’s & endlers

Hello all.

So a few months back I got a 40ish(slightly bigger) gallon tank. I only had a little bristle-nose pleco at the time and he was in a 25gal and I figured it was time for an upgrade. Well since then it was apparently my bright idea to attempt to breed fish(after everything was cycled of course).

I got to the LFS got a endler female and a male guppy as my LFS mentioned it would probably make some cool fish. Wow they bred like crazy — go figure. Well after adjusting, and going through an immense amount of trouble to separate the males and females I finally got them all separated. I figured I’d keep the males and move all the females to my friends beautiful outdoor pond. I go ahead and do that and now all the males are upset, all the endler boys seem to constantly fight, and they’re totally jacking up daddy guppy. If I remove the guppy/ add more guppy’s would that help? Or does it matter? The hybrid boys are stunning and I’d like to keep them. They came out electric orange, black and turquoise. But the male guppy is also rather stunning. In a perfect world they’d all live together but I’m not sure it’s the best thing for them. My friend would happily take anything into her pond so they all have a safe happy home to relocate to, I’m just wondering if there’s anything I can do on my end to keep them together in my tank while also making sure their not fighting constantly. I’m also in the process of setting up a 25 gal for my aging betta(he’s almost 3) and I’m wondering if maybe they could live together? Idk I need tips and suggestions on how to make these fish happy! Currently in the tanks there’s 1 pleco, 3 rummy nose tetras, 5 cardinal tetras, 5 endlers, and 1 guppy, a ghost shrimp, 2 cherry shrimp, and 2 nerite snails(who also get bullied by the hybrids).

 

I think you need more rummynose tetras and Cardinals or a school of fish to break their direct line of sight.
They might be fussy cause you just removed all the females. I am not soo sure about just males cause I always had females with mine. Maybe add more stem plants or females. Or just give it time and see where it goes.

 

I have some endlers that look like your hybrids. I have 2 males and 1 female. Bad odds. Lol

 

I've done a little research into Guppies for my own tank. From what I understand female guppies will co-habitate with each other with little fuss assuming the aquarium is large enough but males will fight among themselves in the absence of females. From what I've read you want a twice as many, or more, females to males to keep them from fighting.
The hybrids are beautiful. If they keep reproducing and don't show signs of deformities you might be able to take them to your LFS for store credit. Maybe bring back new Endlers or Guppies periodically to diversify the gene pool.

Once more I'll say my post is just based on what I've read researching the fish, I can't speak from experience (yet) on this.

 

Ebreus I keep all males together with no issues. I also keep mostly males and fewer number of females with no issues. May depend on the strain.

 

You don't have hybrids. Those are pure endlers; the female endler must have already been pregnant. Breed the virgin females with the male guppy to get true hybrids

I guarantee at least some are. I had the female for over four months and she gave birth on multiple different occasions over that time period. There was no other contact other than with the male guppy ‍♀️ plus yanno I saw them go for it, I guarantee majority are from the male guppy.

 

From what I hear they can retain sperm a year from a single mating.

Nah, they are definitely all pures. I've had male endlers and I can confirm they look exactly like the ones you've included in your pictures, size and everything. Can you provide some pictures of the youngest offspring?

This. Very true. Usually it's around 6 months (7 pregnancies) but can be anywhere from 3 to 12 months (3-14 pregnancies).

Also, might I add that the male endler that would have fathered the pure fry would have been much less inbred than your male guppy, and so his sperm is probably of much higher quality and vigour. I don't see a modern fancy guppy being able to override an endler's sperm deposit. It's very unlikely that your male guppy has hybridised with your endler.

 

It's true that that male black bar endler is not a son of that cobra guppy. She must have stored sperm package(s) of a former mating with an endler male. Yes, female guppies and endlers are able to store sperm packages for over a year. The quality of those sperm packages may become less after storing for such a long time. Does not mean that this cobra guppy has not mated with this female endler in the meantime.

To give a proper answer whether a black bar endler female is able to reproduce phenotypical black bar endler male offspring in the F1 when crossbred with a cobra delta (to use this male shown as an example) male? The answer is "no". But later generations from this line may show a low percentage of phenotypical black bar endler male offspring again. And if the black bar endler male shown in this picture is an F1 male, he won't be a son of this male cobra guppy.

But a female can use multiple sperm packages and the eggs fertilized by these different sperm packages may develop at the same time. Which may result in different looking offspring.
