Psy, the scenario with sumps and filters won't work with Synodontis-eggs......
I had to read that marble-trap spongefilter story
very carefully too; then I found out that the writers
haven't used or tried it themselves
The fly in the ointment is this: fresh laid Synodontis eggs are very, very sticky!

this stickyness disappears after a few hours, but 24 hours or so for sure.
A useful trait for any fish ditching eggs in rockwedges or into sand; the eggs once laid will stay where they are.
the only non-sticky eggs are laid by broodparasite Syno's; the multipunctatus and the "sp Goldeneye".
I use marble-traps
without the sump/filter for petricola-eggs, and the eggs have to be collected from between the marbles.
wich means you have to empty the traps every day to avoid fungus (in the trap water is stagnant, creating bacterial and fungal growth); eggs sticking to marbles or glass bowl have to be wiped carefully from the glass.
luckily that can be done, they're sticky, but not that fragile.
So far I have seen eggs from S petricola, S "petricola dwarf", S polli, S "polli White" (at a breeder), S multipunctatus, S 'goldeneye'; the first 4 species lay sticky eggs the last 2 do not.
Zebrapleco; your 1 and only post on the whole forum is trivial and offtopic; well done
