Ok, we are getting a new and bigger aquarium in a couple weeks (a 75 gallon) for our two piranhas, one pictus catfish, and our algea eater. My question is how do you set up the aquarium correctly so they don't get so shocked that they die? I know I should put the algea eater in there right away but the other fish can go in right away (well after I let it run for a day or so)?
