About Me

  1. 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?
  2. 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.
  3. 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.
  4. 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.
  5. 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?

    Guppies!

    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:
  7. 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.
  8. 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?
  9. 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
  10. 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!
  11. 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!
  12. 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.
  13. 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.
  14. 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?
  15. 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.
  16. 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.
  17. 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.
  18. 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.
  19. 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.
  20. Have a batch of betta fry and noticed an extra fin on one. It's behind the central fin and none of the other fry have this. Has anyone seen this?
  21. I purchased some Blue Velvet shrimp on April 15th from an online retailer and haven't added any other shrimp to the tank. Now my babies are almost all brown. Am I feeding them the wrong foods or did they just have poor genetics?
  22. Anybody know what’s the deal with these white baby bettas. I’m New to breeding.
  23. Hi everyone! So, I'm new to keeping guppies. I just started this year, back in May, and so I'm learning a lot! I have two female guppies sharing a planted long 20 gallon tank with platys and they've been popping out fry like no tomorrow. I've been putting the juvenile fry in a separate tank, but, as usually with guppies, I keep getting more! So, my question. My female mother guppies are HUGE. They are easily three times the size of the boy guppies and bigger than even the platys. Is this normal? Pictured here is the biggest mom (ready to pop with fry, of course): Should I be concerned? I'm sure I'm feeding too much (always trying to feed the fry), and I hear guppies can chest-burst from overfeeding, but I don't know if I'm being overly worried. I'm trying to cut back on the feeding (while also making sure everyone is fed!) Thanks!
  24. So I was given a 5 gallon tank and decided to do a shrimp only tank. I got the 10 pack of cherry shrimp from aqua Huna and they have reproduced like crazy. My only concern with the tank is that all of the shrimp in the tank will eventually be related (if they aren’t already). Does anyone know signs of inbred shrimp that I should expect to eventually pop up? Also, if inbreeding should be a main concern, how often should I introduce new shrimp to the tank? Thanks!
  25. Ars Technica has an interesting article on this topic: The weird genomes of domesticated fish ARSTECHNICA.COM Unlike most domestic animals, the goldfish is purely decorative. One quote: "This week, a huge consortium dropped an analysis of not only a strain of goldfish but 185 different strains. Plus 16 different wild carp genomes for comparison."
