Nice, Eric.

I also uses those boxes when I am in shipping mode. The average time it takes me to empty a tank of decor, catch fish and put things back together is anywhere from 3 to 5 hours in a larger tank.

So I will start pulling the fish a day earlier and overnight them in one of those traps. I can usually get a small piece of wood and some slate si they are not bare. I also cover the box with a towel so it is dark, that way when I am working on other things in that space and have lights on at weird hours the box is dark.

I actually prefer to use what is now called Maracyn Oxy (previously Maroxy) fir fungus. It is colorless. I was taught to use Meth. Blue by a cory breeder many years ago. He told me that as soon as I saw wigglers to remove the blue as it could damage their gills.

Finally, I am not sure that whips do not actually tend eggs. I had a spawns on the front glass from my farlowella and the dad tended and guarded them and I managed to catch this pic. It sure looks like dadt is cleaning the eggs.

I don't usually do much to treat eggs, but when I use meth blue, I was taught just a dip and the MB will soak into the jelly coat of the egg, then you don't have to continuously treat till hatching. But IDK if that really works so well.

I've got video of my male black Rineloricaria lanceolata Rio Itaya using his anal fin and pelvic fins to hop up off the eggs and sweep across the eggs with the anal fin. When I've pulled R. eigenmanni eggs from dad, they rarely do well in terms of hatch rate. It's for this reason that I cut my bamboo pipes to a length that fish like (long enough) to spawn in, but short enough to fit easily in the large size breeder boxes as you've shown. Just like you do with caves, I put the whole bamboo pipe in the box now, dad and eggs inside. I try to wait until the eggs have only 5 or fewer days remaining before hatching (sometimes I cut it close and it's the day before) and like you, I cover the box with a towel for privacy.

Cheers, Eric

I to use the Fluval and I also picked up a Ista which is slightly larger than the Fluval and it has a spraybar on the lift tube so you are adding fresh water across the width of the box instead of just one spot, and the Ista is also less expensive than the Fluval, you can find the Ista at amazon

Oooo. That looks nice. I've never seen that brand.

Thanks Jeanne!

Tonight I dumped the (60+) 1-month-old babies out of the breeder box and into the parents' tank so that I could move the dad with his newest spawn (now 8-day-old eggs about to hatch) into the breeder box. No sooner did I move them than the dad started bouncing on the eggs and the eggs started hatching. I don't know if he was actively helping them hatch or just doing his normal thing a little nervously because of my light... although to clarify, he was doing this before I turned on the camera and its light.

Cheers, Eric

Rineloricaria eigenmanni male stimulating eggs to hatch

Pretty cool Eric, I have video of mine in pre-spawn behavior which went on for hours and now anyone that knows anything about you tube it would take me a year and a half to upload 2hr. of video so I took just the best

Very cool Jeanne! I've never seen mine ever show any behavior like that. My males sit in the bamboo pipes and flip their tails which dangle out of the bamboo, then females approach the bamboo from the male's tail end and enter the cave. Then there are hours or sometimes a day or two of mutual, almost-synchronized, tail-flipping, and then they're finished and she goes her separate way.

Just an aside, I suspect that your video shows two males fighting. I see cheek odontodes on both individuals.

Cheers, Eric

This morning the eggs are all hatched. There are at least 75 baby eigenmanni, but I can't count them accurately because they are scurrying about.

OMG! The dad's eggs just hatched 4 days ago and he's brought home another girl!

Correction, no, not one girl... two females were creamed in that bamboo with him overnight.

I am hoping you meant crammed.

Yes, that's exactly what I meant. There are no eggs yet, so not the other.

This is the kind of typographical error one makes after 2 hours of sleep.

Any other time and I'd edit my post to fix the typo, but your reply makes sense only if I leave it alone, so, why not leave it?

Cheers,
Eric

Now I'm starting to think I was right the first time. The same male is still working with one female in his "home" bamboo. The second female was startled out of his bamboo this morning when I turned the lights on. But big update: when I got home from work tonight, while that male is still working his girl in his cave (no eggs yet), at the same time just 2 inches away is a different bamboo pipe, and there's now a different male on eggs in there. Apparently when the one female was rejected this morning, she said "you snooze, you lose" to the first male, and then she convinced another male to take up a relationship in the other bamboo (which was completely empty this morning) and she got the deed done in just 12 hours! So yeah, not "crammed," but "cr€@med!"

I expect the first male to finish the job tonight, and I bet I awaken to not just the one but two spawns by the morning.

Cheers, Eric

It took another full day for the first male to finish the job, but he did! Two spawns side by side.
