Dont stress. I think these are harder to spawn than hypancistrus.:yes:

Most hypans once they get going you can almost leave them alone to get on with it but with these I have to go through the coldwater change process to try and stir them into action and even then its not a sure fire thing:D.

this morning the female was hoving around the favourite cave, will continue with massive feeding, then a huge cool water change over the weekend, and fingers crossed!

The difficulty lies in water chemistry, imo. They are frickin impossible to spawn, much less get a decent hatch out of unless you're flooding the system with RO. That's what I had to do to get fry.

I believe the long standing belief, which, to some extent, makes sense to me, is that for softwater fish, especially blackwater ones, eggs tend to be less resistant to "normal" microbial attack without the care of the male because the black soup and the subsequently impractically low pH only allows for the culturing of very acidophilic microbiota, which tend to be somewhat slower, metabolically speaking, and just less competitive in neutral aquarium conditions.

When you couple the fact that these eggs are designed to deal with slow growing microbes plus, a lack of microbial activity altogether, you see where the problem might lie.

Of course, if the eggs are actually infertile, not just fungusing, that's a whole 'nother issue.

Here's what I do with my caves to keep the male from kicking the eggs out. I prop the caves up on driftwood or a rock. Just make sure it's a stable prop, so that the cave won't move. If you have a gravel substrate you can pile up some of the gravel and prop it up like that. It works! Mine never kick the eggs out any more. If he disturbs them they just fall back to the nose! Here's a picture of one of my caves that is propped up on driftwood. This batch just hatched out yesterday with a least 150 babies.

GOOD idea! ^^

i'm just going through the neglect period with the again now. no w/c for 2 weeks, then big change and start feeding them up again, see where we get to
