I have learned the same lesson as you with these Fluval breeder boxes in raising Tatia as mine used to get stuck in the foam or in the grill from the outlet. I now exclusively use the Zeiss boxes for Tatia with the inlet higher than the water level, but still use the Fluval boxes for Cory's as they tend to stay on the bottom of the box.

Good luck with these, will be great to see them hatch.

sturiosoma wrote: ↑10 May 2023, 16:38do you think that lowering the water level would concentrate the fertilization process, so in other words apply your trigger but don't fill the tank up as high as you usually do.

Two things: Reading up on raising rarer tetra spawns (also egg scatterers) I have come across two pieces of information that you might want to experiment with. Light sensitivity is a well known issue with tetra eggs and newly hatched fry. We don't talk about light sensitivity much with catfish eggs and fry, but it would seem logical it could be a potential issue with some spp.
Second, some tetra breeders are having success hatching out the eggs in 100% rainwater. I have never experimented with this, but if you are getting constant eggs it could be worth a try. Eggs were simply hatched in a one gallon milk jug (opaque to block light) with a gentle air stone. After yolk absorption they were drip acclimated
to tap and raised without issue.
Just throwing some ideas your way.

"Poor hatch rate" is an understatement... It's zero for the Microglanis.

Cheers,

I understand. I'm already using the needlepoint canvas on the egg catcher, but you're right that the fish can swim anywhere in the 10-gallon tank. The inverted pot with the synodontis-style setup sits atop the egg catcher they're already spawning over, so the pot itself should act as a water barrier to concentrate sperm to fertilize eggs at least as well as the flow-through canvas (which wouldn't restrict water flow or sperm dispersion).

SPAWN #6: I arrived at work today to find 4 eggs in the egg catcher under the Synodontis pot, but the eggs weren't directly beneath the pot... I don't know if these eggs were released inside or outside of the pot but they did fall into the egg catcher.

I don't have rainwater, but I do have RO water. I've moved these four eggs into one of the FLUVAL breeder boxes with an airstone (not bubble-through flow) and I filled the box with RO water, not tank water. Let's see what happens.

If this fails, the other thing I'm contemplating to employ is an actual egg tumbler. I have one of the Cobalt style egg tumblers.

Cheers, Eric

Below is one of the pots I made using the concept for Synodontis but adding a mop inside. I call it "mop-in-a-pot."
