after some thought rather then stickign somthing on top of the filter can i just stick a plant pot ontop of the egg and stick nylon ontop of the plant pot? im not trying to be lazy :S but its a lot easier lol?
that then prevents the fish from eggs going into the filter
and prevents other fish eating the eggs?
No the parents may not keep the eggs clean or the eggs could easily get fungal disease. Find the instructions for your filter and see if you can remove the whole intake tube . You only have a 1 or 2 days before the eggs will hatch if you didn't know this already.
