Hi everyone! I currently have plans to upgrade one of my 10 gallons to a 15 gallon, and I just had a few questions that I thought I'd see if anyone could answer for me. 1) What is the best way to transfer the fish with minimal stress? 2) What percent of the water should I keep from the original tank? 3) Do I need to get a different kind of heater for a bigger tank? Also, I am thinking of having live plants in the 15 gallon as opposed to the artificial ones I have currently. Any advice/recommendations on what kind of plants are good for beginners? If I get live plants, do I need any specific kind of lighting? Thanks!
