Popular Post Johnny B. Goode Posted August 17, 2021 Popular Post Share Posted August 17, 2021 (edited) So a while back I set up a 75 gallon for our 7 year old who is autistic. He wanted glofish gravel with castles and dragons. He loves loaches and decided he wanted only yoyo loaches in the tank. So we got 6 yoyo loaches and that has been the only thing in the tank since it cycled. So, for about the past 3 weeks he has been telling me that there is a baby in the tank. I took this with a grain of salt because when he talks to the fish he says "hi babies". Thinking to myself that is impossible because they don't breed in captivity. Then to my extreme surprise as I was cleaning the tank today lo and behold there is a freaking baby yoyo loach. I've only found the one. I do 50% water changes on this tank once a week and have not seen the baby until today. I want to be 100% clear that this was not an intentional spawning. All I can tell you is the parameters that I know. The temp is 80 with water changes of about 74 degrees. PH 6.8, Ammonia 0 Nitrite 0 Nitrate 10. There is duckweed on the surface with some java moss in the tank. They are fed exclusively on bladder snails, repashy Igapo Explorer and hikari sinking wafers with some frozen blood worms and brine shrimp every couple weeks. You can see how small he still is by the size of the gravel. You can see he's not a whole lot bigger than a piece of gravel. I have no clue how or when this happened but it is pretty amazing. If it ever happens again I'll keep everyone updated. Edited August 17, 2021 by Johnny B. Goode 14 8 Link to comment Share on other sites More sharing options...
Biotope Biologist Posted August 17, 2021 Share Posted August 17, 2021 It's the glo gravel. They put fish pheromones in it that's why it costs so much 1 6 Link to comment Share on other sites More sharing options...
Griznatch Posted August 17, 2021 Share Posted August 17, 2021 Very cool! I still get excited when my guppies and shrimp have babies, and they do it all the time. 1 Link to comment Share on other sites More sharing options...

anewbie Posted August 17, 2021 Share Posted August 17, 2021 Pretty amazing; yoyo loaches almost never breed without assistance of hormon in captive environment. How large are the adults and how long have you had them. Most yoyo i've seen for sale are more than a year from adulthood and your tank doesn't sound that old. Adults can grow over 6 inches but I would think they have to be more than 4.5-5.0 inches before they start breeding. 1 Link to comment Share on other sites More sharing options...
Andy's Fish Den Posted August 17, 2021 Share Posted August 17, 2021 That is so cool! It's especially neat being that they are hardly ever bred in captivity, and that your son noticed the baby fish in the tank. 1 Link to comment Share on other sites More sharing options...

They are about 4 to 4.5 inches with the exception of 2 that are around the 5 to 5.5 mark. The 2 larger ones were returns to the store because the people thought they were too aggressive. I've never seen them be aggressive though. Edit: sorry I missed the part about the age of the tank. This tank has been running for roughly 6 months in its current state. No changes other than water have been made since the addition of the loaches. Edited August 17, 2021 by Johnny B. Goode 2 Link to comment Share on other sites More sharing options...
Dwayne Brown Posted August 17, 2021 Share Posted August 17, 2021 WOW, that incredible! I cant believe you got them to breed in a captive environment. 1 Link to comment Share on other sites More sharing options...

Well if you've had the fishes for 6 months then one has to believe they bred in the tank which is really quite incredible. If you are lucky you will get more. Not sure if you need to give them bbs or whatever to feed them. Please keep us updated as this is rather interesting. Off hand do you know your water condition (ph/kh/gh) ? Just curious. Still now i'm wondering if those colour stones are radioactive and that is why they bred 😉 1 Link to comment Share on other sites More sharing options...

I was just doing my best to keep them happy and healthy. I really believe this has to be a one off fluke situation. I'm not sure why they did or why only one baby popped up. Maybe there was a bunch of eggs but I never noticed them. They do have a lot of caves to hide in though. 1 Link to comment Share on other sites More sharing options...
Deku-Corydoras Posted August 17, 2021 Share Posted August 17, 2021 So apparently the secret to breeding loaches is neon rainbow gravel. 🌈 The more you know! 1 3 Link to comment Share on other sites More sharing options...

Sorry if I’m asking a stupid question I wish there was a justification for the absurd pricing beyond brand recognition. This isn't a slight at OP btw 1 Link to comment Share on other sites More sharing options...
Hobbit Posted August 21, 2021 Share Posted August 21, 2021 I’m in shock!! That’s amazing!!! Have you seen any breeding behavior from them? I don’t even know what breeding behavior is supposed to look like but maybe you do! 😀 1 Link to comment Share on other sites More sharing options...

Chasing each other and being goofballs. All of them trying to get in the same cave because they are crazy and leave the other 10 caves in the tank alone. I really think this was just a one off thing. I didn't try to breed them. I just hit the fish breeding lottery I guess lol. Edited August 23, 2021 by Johnny B. Goode 1 Link to comment Share on other sites More sharing options...
