I personally think large fish are horribly boring and a waste of a large tank. My dream is to eventually get a 300+ gallon with micro fish.
Yeah, it's a good look to have tons of schooling tiny fish together. Centerpiece fish in your 500 gallon would be nice. Say 7 discus for centerpiece then 100 rummy nose, 50 black neons, 100 neons.
...Perfect
I went from a 10g to a 20 to a 30g then two 55g and now a 120g, all small fish. Biggest fish are Angels and a pleco. Big fish are ugly...sorry. =p
