didn't think anything would come of my male longear building a nest but i caught them spawning and now I have eggs. :) dont have a tank for them but what should i expect in the coming days? like how long till they hatch and is there any possibility of them serving in my well planted tank.?

Hatch occurs about 36 hours post-fertilization (spawning).  With Longear Sunfish like you have you need to be prepared for exodus / swimmup / first feeding after another five days.  I strongly suggest you feed with live baby brine shrimp for the first 10 days before transitioning over to some sort of fry feed.  They can survive in the well planted tank if you remove larger fish with possible exception of the father.  Tank size not indicated but I suggest reducing brood size down to about 100 when the leave the nest.  Not natural but father usually will not harm little ones even after they leave the nest.

yeah tank is my 75g main display tank has several other sunfish in it. So moving other fish out not very likely. of my other tanks one is a redfin pickerel grow out tank he would find them yummy of course as would my warmouth tank. That leaves my guppy tank that i use to breed feeders for the pickerel.  the guppies don't seem to eat there young to much. maybe i could mix some fry in.

The guppies will consume the sunfish fry like candy.  The sunfish will not have appropriate responses for avoiding the guppies.  You might be able to place some sunfish fry, about 10 or so, into a livebearer breeder cage and feed tank heavily with BS.  You could rear about 100 sunfish fry in a bare 10-gallon aquarium.
