Welcome and congrats on the new tank but we need more info{we always need more info} tank size,lighting,filter and what are you planning for the goldfish as they are usually cooler temp. fish not to mention your plants look like a Caesar salad to them lol pics are nice too...
The goldfish doesn't belong in a heated tank. They need oxygen rich cooler water.
Also having so few black skirts, they may nip on the goldfish's fins, they can be one of the nastier tetras.
That being said I have kept some in community tanks, but raised them from when they were tiny.
