Still trying (unsuccessfully) to get fry from these guys. I can get them to spawn, but still trying to get the eggs to hatch (and/or not get eaten).

Either way, one of my current favorites. Very personable. Very slow, very peaceful. They love to come up to the glass whenever I approach and say 'Hi'.

Beautiful fish. Do they eat their own eggs?

They do. But I am unsure if the eggs are unviable and they know it, so they eat them. Or if they just eat them cause "why not?"   🤷‍♂️

I've had them spawn 4 times (that I know of) and no eggs have made it through to produce fry. 

I have heard these aren't the easiest fish to breed, so I'm just going to keep trying. Fingers crossed, I'll get fry out of these guys some day.

I’ve heard of breeders of various sensitive egg-eaters blocking off the tank entirely except a tiny gap to check on the fish/eggs/fry.  Dim light only, feeding holes so you don’t have to lift a lid, slow dripping water in with auto-overflow for water changes, and I’m sure there’s other tips out there.  Maybe one or more of these will be the key for your pair.

@Odd Duck and @Beardedbillygoat1975, thanks for the advice. 

Coincidentally, I did actually order a decent Ph meter the other day and am receiving it this week. I recently acquired a couple pairs of Apistogramma Abacaxis and they also require Ph in the 4s to successfully breed. 

All I know with the Ivancara is that their Ph is currently below 6 because that's all I can measure with the common aquarium kits.  So their Ph could be 0 or it could be 5.9, I have no way of knowing. Hopefully the meter will help me get a better idea of where it's at and I can tweak from there.

I haven't seen anything online about their eggs being light sensitive, but I also haven't seen much out there about how to successfully breed them, other than low Ph and clean water. 

The TDS in their water is currently suuuuuper low, so I'm also wondering if I add a teeny-tiny bit of hardness back into the mix, if that may have any impact. However, one change at a time . . . first experiment with the Ph levels and if that doesn't work, maybe introduce a little bit of mineralization into the water.  I have read they come from 'nutrient poor' waters, but how poor is 'nutrient poor'? Dunno. Maybe my current water is like 'nutrient bankrupt'. 

Right now, I can get them to breed no problems. Just can't get any fry.  But . . . maybe my problem is a simple one, the parents eating them! (I did pull the eggs once and put them in a breeder box, but no luck there either. All but a few were infertile and those didn't develop).

Let’s see what happens!! You could always get some r/o water and do a water change after a little bit and see if a simulated dry then rainy season does it. 

They are in RO right now. If I do a water change with cooler RO water, it triggers them. That and feeding live black worms. I seem to be able to trigger them no problems, i just can't get the fry to hatch. Mostly the parents eat the eggs, but when I see the eggs disappearing, it's after a few days, so they either hatch and die or hatch and get eaten, or the female eats the infertile/bad eggs (is that even a thing?). All in all, they have spawned about 5 times.

There is an older YouTube video out there where someone has gotten the fry to hatch and they are following around the mother. The youtuber then mentions that this was something like their 95th try at this. He was so ecstatic with joy.  So, I guess the moral of the story is patience?

If he didn’t mention what he did different to get fry, have you tried reaching out to him?  It’s worth trying. He might have just the suggestion you need to get them to not eat fry or get eggs to hatch.

Many other species will certainly eat bad/fungused eggs and some are sloppy about it and get a lot of good eggs, too. Plus some get started on the bad eggs and just keep eating.

Seems like I saw some breeder of either angels or discus that were persistently eating eggs and he decided they started on fungused and just kept going. He used a pipette and may have calculated his total allowed drops(?) for the tank and flowed methylene blue over the eggs after laying. He did it after lights out and had the tank pretty blacked out, too, if I remember right.

I don’t know why I remember weird tidbits like that, and it was a one-off post on a forum (if I remember right), but something to consider if you think the eggs are fungusing even after fertilization.

Do you have a camera you can set up outside the tank looking at their spawning spot?  You can create a cardboard box to enclose the camera if you want to black out your tank. That might help you figure out if they are eating the eggs, or the eggs are hatching and they are eating fry, or if the fry are dying.

Set up the camera to run continuously but make sure you can review in adjustable speed in fast forward so it doesn’t make huge jumps as you scan through. You might have to hire somebody to review all the footage!  😆

The video is like eight to ten years old or so, if I remember correctly. And, alas, others asked and no replies.

Thanks for all the other tips!

I could just set up a live stream and crowd source it by posting a link here!

We can take it in shifts, right across the globe!  😆 😉
