I know there are thoses that are bred to be glo fish now, but a lot of places near me still sell the dyed ones. And if you are going to try to correct me since I've been in the hobby probably longer I care to admit please use the correct term for the dyed fish which is GLO, not GLOW. Natrual Glow fish are the glow light tetra, and a few other speices.

Glo fish should be out of the hobby. They are a manmade fish. Dye is injected into the fish to make them have that glow appearance. Any dyed fish tend to lead short lives from what I've seen of them.
They are now bred to glow, ethical places no longer inject, there are clear differences now between injected and genetically bred glow fish!

If I recall (and looking at the GloFish website itself), the fish have been genetically modified from the start. I'm unsure of how practical injecting dye into a fish would be, not to mention how tiny a needle you'd need. The official branded and trademarked GloFish are bred to have a gene that was already naturally occuring in other organisms, the first generation of fish is given the gene through genetic modification, and then that gene is passed on to their fry as a normal gene would. To my knowledge the fish have never been dyed, but I'd be interested if you could provide a source on that. From what I've read about them the dye thing is a myth. Here's the official website: Click 
How can you tell the ones you see are dyed as opposed to genetically modified? They naturally produce the protein that causes a glow; as do many other marine species. The only really artificial thing about them is the gene that causes the protein as it wasn't natural in those species and had to be introduced. I'm not trying to be rude here, and neither was the person responding to you. If I've misread your tone please forgive me, but your response did come off as quite abrasive when they were just trying to bring up another point. Those of us that have been in the hobby for a long time can also learn new things, heaven knows I have haha |

Simply put the dye as with the frankenfish blood parrot chichild under the skin kind of like a tattoo. The best way to tell true glow fish is the higher neon and fantasy colors that don't look natural. I know the Glo Barbs are dyed since barbs do not have the natural Glo gene mutation as are the jellybean blood parrot cichilids. Danio's I'm on the fence about, along with certian tetras like the black skrits. Guppies, neon and cardnil tetras tend to mutate in their colors so those are not likely to be dyed if you can confrim the bloodlines. GloFish were originally dyed tetras of either the glow light, or neons, but eventually as they bred the gentic mutation started to occur naturally.

Glofish are genetically altered and are not dyed, nor is the gene something naturally occuring. They have specific genes that were inserted into the progenitor eggs that cause them to glow (hence the name) under black lights, similar to many sea anemones in salt water tanks.

Hawkeye, you are right that there has been dyed fish offered at pet stores (as you mentioned, utilizing an under-skin tattoo with Parrot Cichlids & a few other species) but I think you are confusing these with GloFish. The trademarked GloFish brand fish were never dyed. For all of the species they offer, the early generations were injected with jellyfish or coral DNA while in egg form - not dye. This DNA alteration added fluorescent proteins which give them their glow/color. Now, they breed true. :) I'm a genetics nerd so I couldn't resist having their orange tetras in my dark-toned, naturally scaped tank. They were a beautiful addition and I was very happy with how healthy and resilient they were. |

I could be, but the jellybean blood parots have had the bright neon colors also. They are mostly yellows and pinks. Although with I also see very pale pinks, blues, and yellows as well. I knew about the genetically modifying using something from jellyfish or coral DNA when it came to the original GloLight Danios which were the first fish used to do this with. Did you know the original GloFish were never supposed to be in the pet market, but used for detecting pollution in water? Betta's still aren't exactly bred true for the Glo feautre eventhough I have seen them on the market for astromincal prices. The tiger barb Neon/Glos have only started popping up in the past decade or so. The black skrit tetra was one of the first tetras they did the Glo treatment to to start naturally breeding them.

New to this forum- i have a few tanks- a 10 gal with a common goldfish (he's orange and white- his name's Blaze) a 20 gal community tank with guppies, a female betta (Brooke), and soon a few snails. and a 2 gal with a suprisingly aggresive female betta (Ruby). she likes it for right now- but i want to get her into a 10 gal. i dont have many live plants because my light broke and most of them died, but hoping to buy a new one soon! and my goodness, if little, year ago, beginner me had looked up how fast guppies breed, i wouldnt have got any 😅 i think Golden mystery snails are awesome, and hope to get them for the algae in my 20 gal. i think i can put the snails with my goldfish too, right? i want to get blaze a buddy, but i dont know if i can put more in a 10 gal, can i? |

Do you have a bigger aquarium for Blaze? a 10 gallon is wayy too small, the smallest Blaze should be housed in is 55 gallons though 75-220 gallons would be way more ideal.

Miss me? I missed you guys! I've kept you all in the dark and it's finally time for me to come back and give Hawk a break, I am so sorry for disappearing like that but I can explain. Where have I been? My grandmother has been sick but she's doing okay now though she will be getting transferred to a different hospital, That's all I'm gonna say about that. What have I been doing? Well, I FINALLY finished building my pc omg that took forever. What's next? What do you mean what's next? SCIENCE! That's what's next. Are you gonna do it? The fuuuck? ...OH debunking myths, Yes I will be doing that hopefully more often >..> Unless I 'accidentially' forget During my prolonged break I have been doing a lot more research and I found something fascinating, I will admit that even I had my doubts until I started using it in my 20 gallon aquarium. Brightwell Aquatics MicroBacter Start XLF, I have been injecting this stuff into my filter for about a year now and it's amazing, It basically jump starts your beneficial bacteria, I was experiencing power outages last month and the XLF helped my filter from completely crashing, Now I have so much benefical bacteria in my HOB filter I need to use my fingernail to scrape at my phosphate and ammonia pads so I can see which one is which lol The downside of this product is that a tiny 4oz bottle is around $79+ so it's crazy expensive and is not for everyone. And before you ask, No you still have to clean your filter even if you are using the XLF. Due to my real life I don't have a lot for you guys today but hopefully I will get back into the swing of things eventually, I do have some exciting news this month (Since the weather is FINALLY being nice) I'll be starting work on my 45 gallon aquarium but first I gotta stock up on filter media for my HOB and my Fx2. Speaking of my Fx2 that thing was literally painful to assemble, the the cuffs (What I call the silver thingies that lock the hoses onto the intake/out-take) Yeah the flathead screwdriver kept slipping in my hand and I cut up my hand pretty good (Didn't need stitches but it still sucked) About those myths, NO a fish cannot live in any 'converted' equipment -_- Do you know what KIND of micro-organisims are IN THERE!? That'd be like..Taking the crud out of your eyes..AND EATING IT -Shudders.- NASTY! |
