Hello. I have 10 tropical fish (tetras and some others). I've had the tetras since 2015 and recently purchased the others a week ago. I would love to aquascape the tank, but do not want to cause stress to the fish by moving them to another smaller tank while I decorate the tank. I want some opinions please. Do you think I should proceed or it's not worth it? Right now the tank is very basic with gravel only and a big rock and medium treehouse-like structure. Nothing else, besides the heater, lights, filter, etc.
