About a week or so ago, i was trying to raise my corydora eggs to fry, during this time period i managed to see several fry going across the top of the water column. I had hoped they were corydora fry but i quickly realized they were not. Typically the only thing in that tank are my trio of threadfins, corydora eggs from my main tank, 4 dwarf shrimp, and 4 oto cats. later looking back i realized i had seen threadfin eggs but my brain didn't put two and two together. While looking online for resources about caring for the babies, i realized their wasn't much on the topic, so now i am writing down my conditions in which they spawned so it may help someone else.
- Ten Gallon Tank
- 76 Degrees F
- PH of around 8.4-8.6 (Indiana water is fun)
- Heavily Planted, Pressurized CO2, High Lighting
- Indian Water sprite, Used as a back plant, as well as portions get taken off and float around (this is where the rainbows laid their eggs)
- Run by a Sponge filter
As for the current fry i have seen 7 at the moment, their are more eggs laid and being laid( these guys go around doing mating stuff like once a week), i have kept the fry with the adults and have seen no loses from being eaten. I have intentionally not added more threadfins, to prevent predation. |

Hi! Thanks for starting this thread. I too am working with werneri. I haven't kept them in a long time, and don't remember much of what I did before. I'm sure this will be helpful for a lot of people. Not much info out there on these fish.....I don't know if you saw this before? But Mark did a write up a while ago on how he feeds their tiny fry. Here's the link: rainbowfish.live/thread/82/werneri-first-fry-food-simple |

I'm curious too if they go through spurts of spawning rather than more of a daily thing like other melanotaenia species? Also wondering about the best temperature at which they produce eggs.
55 gallon tank
plants--mainly large anubias, some giant val, and guppy grass
14 males / 12 females
10 panda cories
tons of blue dream shrimp
several < 1" bristlenose pleco babies
lighting, natural sunlight
no heater, but it's getting to be summer now, so tank temp has ranged from 78-82 F
After I moved them to this tank a few weeks ago, I checked the mop not expecting much and there were hundreds of eggs. Now there are only a few when I've checked a couple times per week the last 2 weeks.
The two factors that I think are contributing to the lack of eggs are; the fact the temp went from 78 to 82 F and I added the blue dream shrimp. Every time I check the mop, some shrimp scamper out. I do see a cory check out the mop occasionally, but they were in there before when there were tons of eggs. I'm working on catching the baby plecos as I can; but it is slow going without tearing apart the tank. I have not seen any baby plecos in the mop, but know from experience, they will eat eggs. Adding the shrimp was a spur of the moment thing as I had to tear down some tanks in an emergency to make room for a water heater replacement. I think the commotion from the workers also messed up their breeding cycle.

I know this is a bit late but they do spawn daily, lately i have had to move a blue ram into so she has been eating a lot of those eggs, but she should be out soon
