🔗 Save $1,400 A Year with My Complete Aquarium-Saving Methods I teach: https://isamuyoshida.com The fish store sells you the fish it is today. Your tank has to live with the fish it becomes.

They are the tiny "beginner" tank, the one-inch-per-gallon myth, the idea that fish only grow to fit their tank, bad tankmate pairings, pH-chasing bottles, buying from a sick store tank, and the "algae eater" that grows close to two feet long. You'll also get the one question to ask before you buy any fish.
