This is my first time buying a fish online. When he arrives, are there certain acclimation processes. He's a 5" Flowerhorn going into a 75g with 82' temp, and a ph of 8. There are no tankmates other than a synodontis and no decorations. Though the tank does have a homemade concrete b'ground. I think he may enjoy his new...anyway, anything I need to know?
