Answer
I hate to be the bearer of bad news, but you can't keep that setup.  Goldfish need 20g minimum for each fish, 2 Angels fish need to be in a minimum of 25g for the pair.  The new fish you bought is a common pleco and will get to be 18" long and need at least a 55g.  The Angel fish not eating can be one of two things, your water temperature is too low, they need temps of 80-82F (which is bad for goldfish, they are cold water).  Or they could be suffering from toxic water from an over crowded tank.  10g is too small a volume of water to handle the waste produced from that many fish.  I hope this helps.
