Just wanted to show that at least _these_ Darters (Rainbow & Banded) _do_ eat frozen bloodworms.

Rainbow Darter eating bloodworms…

Banded Darter eating bloodworms…

To be fair, it is a slow process. They’re certainly _not_ voracious yet like many other fish.

This work is incredible! Love Tennessee Aquarium for making and sharing content like this.

Tangerine Darters caught and bred then fry released as “virgin” for mussels to lure and multiply. Just fascinating relationship…

That male is such a looker. When it’s breeding time will you just let it go in there ? Are they known for preying on their young or the other species you have in there? What did you say they were? Are you worried about them eating the fry? Or will there be a spawning tank?

I was just text messaging with my friend, a former NANFA president about this very subject today. These Rainbow Darters (Etheostoma caeruleum) breed in small gravel like this:

He told me that I should consider using a bare tank with a HOB filter and a small tray with this black gravel placed beneath the outflow. The females hop in the gravel tray and bury their body partially down in the gravel. Males jump in . . . the deed is done . . . and eggs are deposited down in the gravel. Then, the tray can be picked out and the eggs can be removed.

The sandy substrate in this tank is not what they'd prefer. Nor is the rough, sharp Eco Complete in my other Rainbow Darter tank.

I see, that’s pretty cool! So they want a decent current and then bury down. Then so what do you think? Put the parents back in the main tank then leave tray and let nature happen or be more cautious and pull the eggs and methane blue or tumble or something? You can probably tell I’m fairly excited for you. Hope you get a lot of this on video.

good luck mate

For a first go at it, if I'm trying to earn BAP for my fish club, I'll pull the tray, sort through the black gravel to find eggs (which are lighter colored) and do the whole m-blue bit.

BUT the other thing my friend told me is that I need to fool them with light by _lessening_ their photo period to 8 hrs a day for a handful of weeks to simulate winter. Then slowly reopen the photo period to simulate spring. Same trick works on other natives.

I’ve not seen my mature pair of Rainbow Darters for awhile - a few weeks - in my 29 gal. tank at work. I feed them every day, assuming they’re in there… but they’ve not made an appearance. So, this afternoon, after a cold water change, I jostled the wood they’ve been known to hide under. Wow! That male and female came out. He’s huge, and totally colored up. I couldn’t snap a photo. But I’ve decided to add more Rainbow Darters to get them displaying. Hopefully I’ll get some awesome shots to post soon…

Alrighty. Today, I’ve moved two young male Rainbow Darters from a 20 gal. long in fishroom over to 29 gal. at Office. The 29 gal. already has a mature pair in. My goal is to witness some seriously colorful displays in the larger tank.

They weren’t terribly difficult to catch…

Showing sone nice colors…

And now adjusting to new tank…

Once they draw out the big male from his lair, there will be rainbow fireworks. Nothing deadly, mind you. I’ll pull them if it’s getting down to injuries. I just want to actually _SEE_ these Darters more.

Plan worked! Rainbow Darters coming out from hiding a lot more now that there are 3x males / 1x female rather than the 1 / 1 ratio. Here’s a couple minutes of “Still Cam” while I left the room. This is edited down from 19-minutes. They’re not terribly social (for me at least), but very interesting when they come out!

how cool! I used to have Orange sided darters, I'm thinking of getting some again this year!

Awesome! I’ve just started down this journey this past year. Got about 6x Banded Darters in this tank. Then about 5x Rainbow Darters in another. I haven’t effectively set up breeding for either one, though I’ve done a fair bit of research.

Walked into my LFS last week, and behold! They had gotten in a fish none of them could ID. Some sort of Darter. I told them she was an Etheostoma of some species, and they asked if I wanted her. Well yes!

Maybe a Johnny Darter, or Tessellated Darter?

In other tanks, my Banded Darters are coloring up with Spring..,

And my Rainbow Darters are too…

This other Rainbow guy is getting big, and likes to hide under the glass cube…

As other US Natives are gearing up to spawn, I am eager to trigger these Banded Darters to lay some eggs. Their tank has kind of been growing lots of duckweed across the top, not getting as frequent water changes as it deserves, and the cheaper powerhead konked out in it. SO! Today was a big upgrade:

(1) Removed broken Powerhead, and replaced with another functioning powerhead attached to a sponge filter intake. This was something that folks mentioned on the Forum. I tested it out in this new 10-gal tank that I got to replace the one that cracked a couple weeks ago...

(2) Removed loads of duckweed, and extra small flowerettes of water lettuce to provide more light, and lengthened the photo period by an hour.

(3) Performed a water change, and fed frozen blood worms

Here is a video showing the tank presently, and explaining my thinking about the breeding process / plan. I suspect that I'll be adding several mops. I've already got one made. I think that mops will provide the context for  spawning that these guys really need. But here's hoping the Java moss looks enticing!
