Eggs not sticking to cone

[davidkirley]

If you watch them spawn are they actually getting the eggs on the cone and there falling off or is the female not making good contact with the cone

Jeanne

They hit the cone and roll down. It's a terrible pic, I admit, but you can see her going up the side and then the eggs just rolling down. This photo was taken during one of the previous spawning attempts.

As for diet, I'm not sure, but I'd like to think that it isn't.

They get frozen beefheart, bloodworms, tetra color granules, and occasionally I'll get some live blackworms from a LFS.

Thanks for all the great feedback! Much appreciated!

Her ovipositor seems to make good contact...look at all those eggs in the bottom, yikes!
Good variety in the dirt as well...it's a mystery I hope someone can solve...

Yeah exactly! Yikes indeed!

I wish I had gotten a video of the male while this is happening. His confused behavior while trying to pass by after her is really funny. Doesn't quite know what to do with all this lol

[danotaylor]

Poor fella, LOL

Cliff with this happening 3-4 spawns in a row is there anything that can be done to correct it? Diet as Pat postulated? Is it a defect in the females reproductive system? Perhaps a maturity issue?? Cheers mate

The pair is genetic weak it might take a few
more spawns for a stronger batch. Could
be from to much inbreeding, line breeding
or just genetic mismatches. I do a
quick fix by switching males or females this works immediately.

Thanks for the explanation, Cliff! Makes perfect sense. Since I don't have any other discus, I'll let them keep trying some more.

Discus can lay their eggs on just about anything. A beer or wine bottle will do. The outer membrane/shell casing isn't devoloped properly yet. Like mentioned above.

I wonder if this could be diet related?
Pat

If this could be diet I'm not seeing any veggies, I would replace the tetra color granules with omega one super color discus pellets, while tetra is a old company the quality of their ingredients has diminished, mostly fillers, wheat flour, soybeans and what not, I try and think of what could the fish find in the wild ,flour and soybeans I don't think so, call me weird but I would try the change if nothing else you'll be getting some veggies in them any thing is worth a try.

What beer bottles do you use LOL.

Great suggestion. I reviewed the ingredients of the omega one pellets you reccomend and the tetra granules. I'm not biologist, but the number of things I can't rightly pronounce is through the roof on the tetra granules. The omega pellets ingredient list is shorter by a significant margin. I'll give them a shot. Thanks!

You could also try Tropical Wild gran. My domestics love it.

Jeanne

I don't use any, but some hatcherys use them. The wine bottles have a better slope than beer bottles. Here is a google with eggs attacted to a bottle.https://www.youtube.com/watch?v=jcce3Wbonzc This is what I found on the outer layer of fish eggs, that might help shed some light. https://www.tandfonline.com/doi/pdf/...50009809386857

As far as using bottles, I have use Calistoga
bottles just add fine sand in the bottle and replace the screw top. The sand adds weight
so the Discus can't move the bottle.

I'll give it a shot soon! The omega one pellets arrived today and I added them into the rotation.

That was an interesting read! I'm guessing that the attaching filaments referenced there are the missing link (pun intended) when it comes to my female's egg production.

That's a clever way to cut down on costs, for sure!
