Help, AngelFish Babies

I just did a water change in my 20 gallon tank with 2 angel fish, a rainbow shark, and 2 horned snails. After I was done adding water to the tank I noticed eggs on the heater and the glass by the heater. There aren't a ton of them I probably destroyed most of them changing the water
I don't have the optimism that any of them will live as I've heard fish eggs on a heater is bad and I have no idea how long they've been on there.
Just wondering what I should do from here on out with the eggs, will they live? Should I quarantine them? Should I leave them alone?
Any advice appreciated.

 

Let nature take its course. If you're not set up or ready for them, or have a rainbow shark with them, its best to let tank mates eat the eggs and/or fry. I have a cory that lays eggs constantly and only once has a single egg made it. And I'm talking hundreds and hundreds every couple months.

If theyre still there in a few days and white & fuzzy, clean them out of the tank as theyre molding. If theyre fertilized it'll take 2 1/2 days or so for them to hatch at which point theyll be free food for the sharks.

 

Usually angels will take care of their fry until they're free swimming. I'm not real experienced with angels, so hopefully someone else can chime in. But..

If this is their first brood, I would assume most of them probably won't live, because they are an inexperienced pair (usual with cichlids). But the more they mate, the higher the survival rate should be. Have you noticed them pecking at the glass? I do know angels 'clean' the surface of where-ever their setting up to breed, this is like their nest. They generally defend their nest from other fish (so it's great the angels are the only middle swimmers). They'll only lay their eggs on smooth surfaces, so if you don't have any smooth faced rocks, plants with large, broad leaves or a 'breeding cone', the glass/heater is their next best option.

I'm not sure of the best coarse of action, so take this with a grain of salt, but I would leave them alone for now, see how the angels take care of them. If they do, you should remove the babies once the parents stop defending them, usually cichlids will turn on their young when they're ready to breed again. If they don't, I would add some breeding surfaces for them and wait until they breed again. Again though, I'm not very experienced in keeping angels.
Edit: someone call me out if I've listed some misinformation. I don't 'know' these things from practice but from reading/research so..my sources may not be valid?

 

Alright thank you

 

You would need to get the other fish out if you wanted them to survive, however, to be completely blunt your tank isn't big enough for one angel and fish much less two. As soon as the lights go out the angels will not be able to see and the sharks (which need a 55 for territory and attitude reasons) will eat the eggs.

I only have 1 shark but yeah I know it's too small for them I'm working on getting them a 60 gallon as soon as I can. I got them all when they were really small and now that they're bigger they definitely need an upgrade.
