Hello, I just found eggs in our new 70 gal. tank.

we have had the tank about 3-4 weeks. I have 2 reg. plecos and 2 little catfish and 1 large angel fish. There were eggs in the corner about 1/2 way up the tank. Some were solid white mixed with some that were clear. Basically round. Which fish are they from? What do I do now. I thought they were too small still to lay eggs. I had to take my large angel out because he just kept eating them up. Anyone with info on eggs and what to do now we would really appreciate the help.
