Rosy Red Minnows - For Enjoyment.

Hello! I have no idea if Rosy Reds are Cyprinids or not, and I don't really have a ton of time to research the name right now. This seems like where they might fit, but if this is in the wrong spot, sorry!

I've got a 10 gallon set up for breeding pest snails to feed my puffer, as well as for housing a few plants and inverts. It runs at room temp (70-74), and has a cycled filter. I was looking around and considered getting some White Clouds to try out, but I didn't really want to spend much more than a couple dollars for a decent sized school. Enter Rosy Reds.

I looked around online and learned that they're actually a variation of Fathead Minnows... which is actually something I've kept before. My dad would use them for fishing on occasion, and I remember keeping a few in a big ole flower pot. Probably like 15 gallons, and it sat outside. Those fish lived for several years, through 100 degree summers and freezing winters. Pretty hardy stuff. I saw that the minimum tank size seems to be 5-10 gallons, so I went to Petsmart and picked up a few. I told her to pick me out 5 or 6 of the healthy looking ones, and I ended up with 10 mixed individuals. I was shooting for 6, as I expected around half to die... now I'm stuck with 10 healthy looking minnows. Some may deteriorate soon, but they look good as of now. They aren't full grown, either - how overstocked am I? Should I wait till they sex out and then keep a certain M/F ratio? I don't mind having to keep up with water changes until they're mature enough to sex, if I decide to go that route. I'd like to see some breeding behavior, even if I don't get any fry. I find it fascinating.

They're a little messy, but something like two 50% water changes weekly should work.

So you think I'd be okay to keep all 10? I don't mind thinning out the crowd, but I feel like I'm gonna have a tough time to find someone that'll take them. Maybe my LFS, but they'll just go back into a feeder tank.

As far as the two 50%'s a week, that's not a problem.

You should probably plan on upgrading to a larger tank eventually or rehoming a few of them, but they should be fine for now. Maybe they could be a good excuse to start a pond

I wish! I live with my parents for now, and will be moving into an apartment soon. A pond just isn't in the cards for a few years!

I'm probably sticking with the 10 gallon, or at most a 20 long at some point. I'm all good with rehoming some of them, though!

Just thought I'd share the set-up, now that it's settled in a bit. All 10 minnows have made it so far, and only one seems to be doing somewhat poorly. He's alive, eating, and doesn't seem super stressed, but he's hiding a lot more than the other 9. He is also the smallest of them, so possibly it's just his smaller size.

I ended up losing one minnow yesterday. I think he died from ammonia burn, as his gills had been particularly red the entire time I had him - all fish show signs of ammonia burn, while the tank is actually testing at 0 PPM ammonia and nitrite. The other 9 seem to be doing okay.

that setup is find but what would be better would be more cover. The more cover spots you have, the more they all can claI'm a "home". They probably all hang out under that drift wood and the males might fight over the tiny spots to breed.

Actually, no, they don't all hang out under the wood. There's rarely one under there, actually.

I do agree that they could use more caves, but these fish aren't really looking for places to hide.
