What’s this? Gold?!? A mysterious Endler fry…


Recommended Posts

Catching this thread late, but I've had endlers before and have seen occasional gold or blonde babies. Maybe 1 in 50 or 1 in 100? And it's definitely a yes or no, not a shades of grey scenario. 

My colony had a couple of tiger endlers in the mix (guppy genes), and was not pure wild-type. I wonder if that brightness from the tigers is what causes this switch to flip? @TheSwissAquarist does your group have the tigers?

My theory (definitely not a geneticist or even had a gold) but could it be recessive albinism or no/ low production of pigments?

Nope. 😂 The dad:

@TheSwissAquarist keep us update on the growth of this fish, id like to see what it looks like as it grows up.

You’re not the only one…😁

Technically if albinism is a recessive trait then the dad could be heterozygous Aa and still not express the trait, kinda nullified the fact that the baby doesn’t have a red eye

so the endler must shoot water out of its mouth like an archerfish to type...

Na I use my little pectoral fins

You also could try isolating the mother and father from the rest to determine the radio of gold to regular fry

There’s about 5 or 6 females in that tank and I have no idea who the mother is. All I know is that the females are uniformly grey. I started this colony with 1 male, 2 females; and I think this is my 5th generation. 
Jeez they breed fast! 

P.S. Have fun at school @The endler guy. It’s the holidays over here. 😂

@TheSwissAquaristwinter break?

thats livebearers for you when i first got platies, i didnt realize i bought i pregnant fish, 3days later, completely out of the blue i had fry.

if you had the space/time it would be awesome if you could experiment with this. Take each female, isolate it for a few months, introduce it to one male, check the offspring, repeat for every female, crossing every female with every male, as i said tim consuming and space needing.

I have ap bio today so I may ask my teacher about it (especially because we are doing genetics/ dna!)

lucky! i did "life science" last year, and am doing Biology next year, but this year im on chemistry 😒

Haha lol, I have science Olympiad from today to Saturday (I have to stay after and then come In Saturday)

I do not have enough experience with Poecilia genetics to be dogmatic here.  But it’s a fun thing to find specially colored fry anywhere!

(1) If it has a red eye, this is an occurrence of albinism. This does occur, and can be passed along. But may lie recessive and unexpressed for generations.

(2) If it is white but without a red eye, this may be a form of leucism. I happen to have a Mountain Redbelly Dace with what appears to be leucistic coloration...

Compared to normal fry…

(3) Xanthism is a slightly different condition that renders fish bright yellow / gold. For example, I have a sport fish (largemouth bass) mounted on the wall of my fishroom — I caught it as a kid…

Just in the news yesterday, I came across an article featuring a xanthic bass caught in a river in Virginia…

(4) Golden body forms are reasonably common in the world of Guppies. Whether that is “xanthism” or just other genetic factors, I cannot say. Certain genetic traits are directly transferrable from parent to offspring. Other traits show up in 2nd generation offspring.

(5) To bring out traits among Livebearers, I know that pulling, separating, snd culling is essential. I bought some guppies this past year…

But once fry began to develop, the colors were all over the place…

However, my son found a single pair of fry that express some nice colors we we aimed for. And he promptly stole them for his tank 😂

(6) To begin down the road with Punnet Squares to predict genetic traits in offspring, you need to understand that this is just the very start of a much more complex puzzle. @Theplatymaster asked about platy genetics on another thread. I’ll start to answer here. Let’s say, for example, that you want to breed fish with blue fins. But you have one parent with blue fins and another with yellow fins. Fin color is just one trait among many variables. But when they cross, if mendellian genetics holds in its simplest form, the dominant / non-dominant traits could look like this:

-1- let Yellow be a dominant color, and Blue be non-dominant

-2- let one parent be: b / b — expressing Blue as both genetic fin color variables, and let the other parent be: Y / Y — expressing Yellow as both genetic fin color variables. (Note: typically this is _not_ the starting point, but for _simplicity_ this will be the easiest place to begin)

-3- the crossing could be expressed like this (pardon the nasty hand-written graphic)…

In this scenario, _all four quarters of the fry will _appear_ Yellow. But now, when these fry are crossed, the most basic expression looks like this…

Here, the lower right square shows up as the desired: b / b. In other words, 25% of these fry will be blue-finned. But now if you cross these: b / b with each other, 100% of those fry (third generation from start) will be all blue-finned because…

(7) This gets so, so complicated because female Poecilia hold onto milt from multiple males, and can mix those genes in along the way if they ever have been exposed to other lines.

I’d explain more, but have to go care for kids just now. (They have my crazy genes 🤣🤣🤣)

Could work, but the amount of time I would spend doing water changes would be phenomenal 😂
