It sounds like you have given your seeds a good start. I have germinated Anthurium seeds from several different species this way (an enclosed container of moist sphagnum moss) and had near 100% germination. The only thing I'm not clear about from your description is whether you removed the seeds from the berries. Typically I remove all of the "fruit" surrounding the seeds.
You will want to monitor your seeds to make sure there is not any mold growing on them or anywhere in the enclosure. If there is, you can spritz that with diluted apple cider vinegar.
You asked about when to take them out. I would wait until you have a couple of leaves developing and then you can gently separate the seedlings and pot them individually. This probably gives them the best chance to develop healthy roots.
There was an article "Growing aroids from seed" in Aroideana volume 35 (2012) that describes the methods that some of our members, myself included, have used to germinate aroids.
Good luck and don't forget to update us in a few weeks!
