I am breeding Cauliflower Swordtails and some of the offspring are short fin. Will they carry the long-fin gene and potentially carry it on in future breeding?

So a rather unique opportunity has presented itself. The 33 gal tank I'm redoing gave me a surprise - a single surviving guppy fry! As it's been growing, I believe it is female. Because she's the only survivor, I know she is a virgin which is rather rare with female guppies, right? I think I need to seize this opportunity and get her a boyfriend. Because I know he'll be the daddy, I'm looking for a spectacular male. Any ideas on where to find one? Suggestions on line? Etc. Female is a dragon mosaic much like this female:

So i found this guy at the cone feeder today. I believe its a lack of pigment but only on the mid flank both sides. Pie-bald ish. There are a few with this higher pink / less pattern that have shown in this F1 batch. They eat and have grown similar to siblings so far. Could be a weird phase or fatal mutation but it looked to neat to not share.

Since we are well on the way to having plenty of puffers up here I have decided to explore genetics by starting to focus on discovering and developing desireable morphs should any naturally occur in F1 batches of my pao cf palustris fry. Has anyone gone down the rabbit hole in developing a parallel morph strain of a species for some desireable trait? What did you learn? What were the end results? I did make a cool platy strain way way back as a 12 year old. This idea seems to be a fun one to work on even if it only teaches me more about the puffers and never ends up with a result it will still keep the project interesting for me.

Like what traits are dominant, recessive, co-dominant, etc. I'm wanting to do some guppy breeding to figure out how colors, patterns, tail shape and size, etc interact but I'm not finding too much on the different traits that guppies have and how they present phenotype-wise.

I recently got into breeding the german blue rams and got a pair of Black rams. They have breed a couple of times but I don’t know how to keep the genes healthy and not excessively line breed them. Do I need to buy just black rams from a different breeder or can I breed the with regular rams and the breed them to black again? How can I do this?

Has anyone ever seen a golden veil angelfish crossbred with a zebra angel?

Hey all, I've recently become pretty fascinated about the world of guppy genetics and selective breeding! I'm trying to read and watch as much as I can to learn about the topic and would love to try and develop my own strain. I have a couple of preliminary questions: 1. How can you know the phenotype traits of a female? Do you just have to breed her with a male and see what the offspring throw? 2. In regards to genetic diversity, are there any rules/guiding principles in regards to breeding 'new' guppies into a line that youre trying to set in order to increase the genetic diversity, or is this not advised? 3. When trying to create variations/lines, do most people have an end goal in mind and breed for that objective, or do they see what a certain guppy with throw, cull to what they like and watch it develop over the generations? I would love any other insight that you may have - any fun facts or cool stories that you'd like to share. As I said, Im pretty intrigued by it at the moment.

Hey guys, Here is a cool article I found. It is on the classification of species within the subfamily Corydoradinae, specifically the genera Corydoras, Brochis, Scleromystax, and Aspidoras. Just something I thought was interesting and worth sharing. https://corydoras.zone/fish/corys/corydoradinae-corydoras-lineages/. One fact I found particularly interesting is that Corydoras habrosus is not in the same clade as C. pygmaeus and C. hastatus, and instead more closely related to the short-snouted clade containing C. panda and C. sterbai, amongst others. The website also has some other pretty good articles to read as well. I recommend checking them out.

Today,I found 2 molts in my blue dream tank and found this guy. Almost brown-black. I am certain this color of shrimp was not in the tank before. Once molt, darker blue dream gets this color or is it because my substrate is black color, all of my blue dream would turn this color eventually? I have very bright sky blue colored Dream blue shrimp. Sky blue shrimp stays bright blue.... Darker ocean blue stays ocean blue but what is happening on this guy? I did not want him to breed this color in the tank so took him out for now.

Hi everyone, randomly what percentage of the plants in the hobby are essentially the same genetically speaking? Since a lot of the time plants like water sprite, anubias, pearl weed, etc are all propagated by just cutting parts off and planting them. I'm excited for what some people from the industry, like @Cory have to say about this.

I've seen locally of sales of mixed coloured cherry (neocaridinas) shrimps for a "skittles" tanks. I was wondering what colour offsprings you may get. Would a yellow shrimp and a blue shrimp, for example, have a chance of producing a green one, like mixing paint? Or would it be more likely to get yellow or green, and even brown, reverting back to the wild type?

Hello I had a dream once where I was at my lfs and I saw a butterfly discus with half lime green stripes and half our stripes and that had been my dream mutation that doesn’t exist ever since and I wanted to know what everyone else’s where- 15 replies

Will Sarasa comets breed true? In other words, Sarasa crossed with Sarasa will result in all Sarasa's? Or some solid silvers and golds? Thanks for your input!

If I adopt guppy fry from all the same mother, will the coming generations of offspring develop fading colours? Weaker immune systems etc? I think I already know the answer, but if you have anything more to add then please do!

So I found what I thought was an an amazing looking juvenile male guppy in my "cull" tank this June. I call him Mr. Marble because he reminds me of a blue marble betta coloration. So I shared his photo on Facebook and asked opinions on trying to create my own guppy strain from him... well I was talked down to by a guppy YouTube personality that I made a mutt and well I almost gave up the hobby. A few weeks went and I said Self who cares what he says put him in a tank and try to make more. So 6 months later and I have a mini Mr Marble. I still have a long way to go but I am excited that I am on the right track... I hope. I have a few more juveniles males that look like they will look at lot like dad and brother and in another week or two I should know for sure. I believe Mr Marble came from a blue and white strain ive been developing for just under 2 years now I call Blue Dreams but because he was in my cull tank I can't be sure. I have no idea if anyone else would ever be interested in my blue marble guppies if in a few years I can claim it as a set strain because they are short tails but I love them. The females are starting to get some white coloration on their top lines. Anyways I will share some photos and you can let you me know your thoughts. I shared the long tail blue dreams I think is where he popped up from.

Anyone who knows me knows that I LOVE angelfish. I came across this article explaing the recessive and dominant genes of an angelfish. Keep in mind that when breeding angelfish this isn't a must have information all though it can be very helpful when trying to breed a desired trait for an angelfish. This a very interesting read and I reccemend it to any nerm that likes sience or biology. https://pethelpful.com/fish-aquariums/How-to-keep-Angelfish-Tropical-Tank-Set-Up Here are the recessive and dominant genes in a angelfish: Common Phenotype Genetic Symbol Domestic Silver + Dark D Marble M Gold Marbled Gm Gold g Zebra Z Sripeless S Smokey Sm Veiled V Streaked St Pearlscale P Albino a a Capitol letter being a dominot gene and lowercase being a recessive gene.

Here's an update on the blue marble guppy strain I am creating. Im getting more and more males coloring up like dad. I caught dad Mr Marble himself as well as several juvenile males in different stages of development of the body pattern and a young female that is getting white on the top line too.

I have seen multiple pictures of rainbowfish online, all of which have what I thought was a stress stripe when it was on mine. I wanted to know if this is a stress bar and if it is why are they so prone to stress? And if it isn't, why is it that my rainbowfish stripes will come and go, but will usually be visibile. Heres an example: I have noticed on my rainbows that there colors fade when they display this stripe (which is what I thought a stress sign), and I saw from another forum member today the same thing! I have also kept threadfin rainbows and they didn't have any of that stripe. I am wondering if its just usually on "bigger" rainbow species. Maybe its just the Rainbow Fish genetics?

I got some free guppies to add to my growing tank addiction and I've fallen crazy in love with them! There's a male and female in the group with blue eyes and they're just stunning. A quick google search of "blue eye red guppy" and "red guppy with blue eyes" gave me pretty much nothing so I was wondering... any chance this is actually something quite special that I should dedicate a breeding project to?? I apologize that these photos are no good... they absolutely do not do them justice. The blue eye especially on the girl is like a lampeye killifish, and the male has quite the impressive dorsal. Both are iridescent under the right light, too! One of my week-old fry also has blue eyes so I'm hoping she's similar.

This is the best pic I could get as this is the first time I have seen it, but I have Panda Cories and Emerald Cories breeding freely in my tank and there is a fry that does not look like either species. I just seen this Cory with brown markings and IDK if there is a possibility that it could have come as an egg on a plant leaf or root or if it could be a hybrid of the 2 fish?? And if it is a hybrid could it breed with it's siblings it would it be infertile?? I would love to hear about hybridization of any other Cory species as well as I have just now found out that they can interbreed sometimes.

First off: M E R R Y C H R I S T M A S ! (or as my little brother says, "MERRY GRIMMACE!") So . . . not an advanced breeder (yet) . . . but enjoyed a talk Greg Sage gave on selective breeding at our Fish Club last year (pre-COVID). He has some really cool fish, and lots of experience to draw from. Check out his work over at selectaquatics.com We have enjoyed breeding Rams for awhile, and ended up crossing a Gold Ram with an Electric Blue. The fry came out mixed, with either blue dominant and gold recessive, or gold dominant and blue recessive -- but the fry all articulated aspects of both, once they matured. If I understand right (and from Greg Sage's talk) they were heterozygous. But eventually, we crossed the fry -- blue with blue, and gold with gold. And a little bit of "magic" sparked. Here was what one of the _females_ looked like from the blue / blue heterozygous crossing: And here is what the gold / gold rams looked like (note the blue-flame highlights on a few of the males): I know that Tom (aka the coral bandit / the ram bandit) has been trying to selectively breed towards a line of red rams. I'm thinking that Rams are a bit more friendly to selective breeding for color strains than is commonly thought. The Black / Dark Night Rams . . . and the Blue Frost coloration are just two that have been worked on in recent years. Anyway, I'm curious what colorations anyone here has been working on with different species of fish.- 9 replies

I have a pair of double dose Philippine blue angels that I need some help with. They have been incredible parents after their 5th try. Raising about 50-60 fry, some veiled and some Reg and they have laid again for the second time since having a successful batch they they have raised to a tad under dime size. The first time they laid after the successful fry, dad was steering the fry towards the eggs and almost encouraging them to eat the eggs. I was concerned to say the least once I saw they laid again, but there was no downside after all. This time the fry are much larger and I fear that the parents may kill the fry to protect the new eggs. So far they have not, but they are not herding the fry to food or showing any parental signs whatsoever. My question is if we should pull the fry or parents and put them in our 75gal community to ensure the babies get to grow up... thank you in advance, just do not want to lose the fry. photos/ vids by request.

Anyone got a list of all the guppy deformities?
giantlumberjack posted a topic in General Discussion
I was thinking of breeding my guppies again but this time i want to do it right. I was searching for a list on everything you should watch out for but i cant find anything on what genetic traits you should cull. Does anyone here have an image or list of some kind about this? I know bent spines and tumors are some but is that it? Some of my adults males have this weird puffed up chest, is that one too? -
So, when I was a young boy and I purchased Black AngelFish I would get a black fish. Today I see people advertise black or double black or even double dark black angel fish. What you end up with is a grey or Smokey kind of looking fish. A while back I started to selective breed my darkest fish to see if I could get a truly black angelfish. I was just wondering if anyone else has done anything like this? I apologize for quality of photo, this is the current fish (and Darkest) I am working with. Brian
