I find that corys prefer to lay eggs on the glass rather then objects placed around the tank in a specific location. You can tell they're duds if they turn white and or are fuzzy. Expect a longer then normal egg period. 4>-<9 days.kakojones;1361512; said:of the cories and ottos there are two each. the danios and tetras are 5 each.
so, probably the cories? I thought they stuck there eggs on a horizontal surface and not vertical.
I guess I'll just leave them for now, how long before I know they're duds?
and thanks for the quick responses on this one.
