yeah, california is crawling with things that don't belong here. i am not sure if i have ever caught a truly native fish here. probably wouldn't even recognize one if i did. its a shame.

It's a funny thought, I hadn't thought of fathead minnows as an introduced species in CA but it makes sense they would be (along with how many others?). Sure, they might work with rainbow shiners...


I just found a Ma population considerably further east than Hartel listed in Inland Fishes...
Fired up males were guarding tiers of stacked rock like apartment floors.
Looked like coral reef fish. Had no idea what the heck I was looking at!
Only think of them as "toughies" or "rosy reds", never knew how purty they are.
Gonna get some.

Hello people from the forum,


I hope someone is going to reply on this;
Reading this E-mail correspondence about rainbow shiners answered most of my questions about these fishes I am going to obtain next week, I am really curious if it will be the blue or more red variety. The guy who ordered these fishes as well; let me know how they are doing when they arive in your tank in USA,I will do the same when I get them next week or the following weeks.
Relatively cool I interpret as around 20 C as maximum temperature, and the red variety can do a little warmer, the blue must go cooler Is this correct?.
This is very important, as temperature rise at the moment to the 30's C in the Netherlands, and my tanks in the shad, temps rise to 24C, the tubs in the shade in the garden do better with 21 C as max.
The Netherlands has also many invasive species as well, like lepomis gibbosus, Umbra limi e.o.. I learned you get the carp from Europe and the snakehead from Thailand which is finishing the rest of your fishes, like the nile perch of Lake Victoria?. It is a responsability of us all to prefend invasive species to spread.

You're mostly right, Casper, but the rainbows can probably tolerate in the mid-20's C as long as there is water movement.

If it's any consolation Mazurel, here in England we're in the middle of an exceptional heatwave. My rainbow shiners are kept in an outdoor unheated fish house and over the last couple of days the water temperature has been up to 28C and the rainbows haven't seemed bothered at all by that. However, while on the subject of temperatures for rainbows could anybody offer advice on (i) the ideal breeding temperature and (ii) the lowest winter temperature they could be expected to tolerate. The last winter in England was unusually cold with water at 2C for many days at a time. If we get the same again next winter I'd move them indoors unless anyone can convince me they'd be OK.

In northeast Alabama water temperatures can go down near freezing for days at a time in the winter. If the water is flowing, I don't think temperatures as low as 2 C would be bad for the fish as long as they had been acclimated down to those temperatures.

I've had several generations of rainbow shiners kept indoors at 17 to 29 C (65 to 85 F). Ive seen spawning behavior at all temps within that range, but above 27C fewer eggs hatch and some develop crooked spines. So I'd suggest 15 to 25C for breeding. Adults seem perfectly happy at the high end, but this strain came from a warm-water stream (Centreville AL).

Re Bruce's comment about acclimation to cold, keep in mind a small garden pond or outdoor tank can heat or cool a lot faster than a stream. You could put in a low-watt heater like those made for bird-baths in a low-flow corner of the pond so they have a slightly warm refuge, or under a large plastic tub floated upside-down, so fish can come & go through the open bottom.

Thanks for the advice guys. I like the idea of a low-level heater and upturned box - just in case! My intention was to keep them in the unheated fish house permanently now so they certainly would slowly acclimatise to progressively lower temperatures as the seasons turned.

Hello,
Thanks to the forum for all the information. Today I fetched my rainbowshiners in the shop in Amsterdam, I bought eight, but I have intention to buy two more, one should be for free, as it is missing one eye.
They do look beautiful, so much fun to look at them.My friends over from California are also curious to see these fishes, as they are from your country...
I put them in my 200 liter tank, 19 C with enough flow and plants. They seem happy to eat daphnia bloodworms and muskitolarvae which in I am breeding myself in tanks outside.
When the females are ready I am going to try to let them spawn with a shale with gravel in the tank next week, brine shrimp I got already aw well, we will see.>

I am sorry, I cannot make a picture from them at the moment. but the males have a lot of bleu. All fishes have a orange horizontal stripe on their body's, beautiful. They are really nice and now 2 august all very healthy swimming in their tank, I got the temp still on 20 C, which they are happy with.I am very busy to install a new 200 ltr. tank in my fishroom, but tough luck it was leaking.When the tank is finished, I like to try to breed with my red shiners, just when it is still possible this time of the year.
