Gourami...Pink Kissing Fish

Question
Chris,
   My question is to do with the Pink Kissing Fish also known as Pink Gourami. I have two Pink Kissing Fish and two albino frogs and also two South American Chicilids. They are all in a 20 gallon tank with a nice size filter, one large live plant, one fake plant, one plant that once was just a bulb and is small in size but slowly developing, and a rock window.
     Recently about a month ago, I didn't notice any eggs or anything in the tank. I came home from work and seen at least 50 baby fish swimming in the tank. (At that time I had more fish such as bala sharks, but died don't know why or how but they looked like they had breathing problems or something.)After noticing the baby fish I put them in the breeder but weren't there long. They died.
      Tonight I noticed eggs everywhere stuck to the gravel in the tank and was basically wondering what I should do with the eggs. I removed as many as I can and put them in a breeder but are they fertilized eggs? I have recently read articles stating that once they are fertilized they will float. I am really confused and hope that I am doing the correct thing by transferring them from the tank to the breeder away from the other fish.
    I would really like to know at this point what I am doing. This is my first tank and these were the first fish i have picked out for the tank. I went through many fish but now am stuck trying to learn what to do with gourami eggs.
    I also have a second question in which regards to the albino frogs. Lately I noticed they had black spots on their toes. What do you think this is. I have been researching on both questions but feel as if i haven't received any answers. Can you please help?

Answer
Hi Dawn;

Kissing gourami eggs do indeed float. I think it was your cichlids. Leave the babies with them if you see more. They are excellent parents.

The trouble you may have is aggression toward the gouramis and frogs. Cichlids fiercely protect their young. If they get ugly with the others, move the gouramis to a separate tank.

If the frogs seem to be okay otherwise, it may just be a normal color change. However, sometimes fish will bite the toes of frogs and cause injury because they think the toes are food. They look a bit like worms to the fish, or the cichlids attacked the frogs and got hold of their toes. Soumds like you need a second tank!

Good luck with those guys......
