Advice, my Dwarf Gouramis are building a bubble nest.?

Here's the tank: 10 gal., a large filter taking up one corner of the tank (unfortunetly no heater), 2 male %26amp; female gouramis, and 1 goldfish, some fake plants and those aquarium pebbles at the bottom. My female gourami hides behind the filter in the corner and she has a mess of bubbles at the surface of where she is, while the male swims around and makes bubbles for the nest. Why do you suggest I do to make spawning comfortable for them?Advice, my Dwarf Gouramis are building a bubble nest.?
get the female out as soon as she lays eggs, turn off filter,get the other fish out or at least separated let the male and female together after the female leaves from laying eggs leave the male in and let him care for the eggs till they hatch then take him out when they hatch and feed then the micro worms through and eye dropperAdvice, my Dwarf Gouramis are building a bubble nest.?
Take out the rest of the fish. Feed your fish live food and get a heater and set it at 79-80F.
There's a good fact sheet about the Dwarf Gourami on this page

The info on removing the female is accurate, as the dad will tend to the nest and the spawn.
Add some java moss and remove the tank mates.
take out the gold fish and you should be fine cause the gold fish is dumb and will try eating the eggs and the male will attack it and kill it
