Auchenipterichthys coracoideus spawned!

[Shaun]

I have 1 male, 2 female Zamora Catfish and yesterday they spawned, I didn't make any observations as I was out all day. When I got home the filter intake was covered in large, whitish eggs. They appear to be fertile and I've moved them into a fry raiser. The only other fish in the tank are some juvenile Corydoras rabauti and they eggs are too big to be from them.
Leading up to the spawn one of the females was VERY gravid, so much so that I was starting to get worried that something was wrong. She is now looking more normal sized, not so fat! Also leading up to yesterday they seemed slightly aggressive towards each other, and were occasionally nipping fins and causing minor injuries. I was going to separate them...
The water conditions are just normal tapwater, pH 7(ish) and conductivity about 300 according to an electronic meter I had a lend of the other day. Haven't tested GH and KH for a while I have done a few large water changes recently with the replacement water going in pretty cold, dechlorinated out of the tap. Its winter here, and normally I age, aerate and warm up the new water.

Will report on what happens with the eggs.

For them to be Auchenipterichthys eggs, they should look like a gelatinous egg mass with VERY clear eggs suspended in it rather than large distinct white eggs.

It sounds a bit more like your Corydoras have spawned. Post some pics.

The eggs are pretty clear, only slightly whitish. Could this be a sign of infertility? Could the gelatinous mass have been sucked into the filter? The eggs were all on the filter inlet, never had Corys spawn in this way, always on the glass or placed in amongst plants. Besides the Corys in the tank are far too small to have produced eggs of this size, they're tiny, I was worried about the Zamora cats attempting to eat them overnight, but I had to move them out of my quarantine tank to use for some other new purchases.
