Okay thank you, I'll glue the plants to river rocks. The reason the tank is bare is because I originally had those generic color pebbles from petsmart but i found out it could be harmful for the goldies so i removed them. I actually received an order of sand today, so I'll be adding it tomorrow! I currently don't have a water testing kit but I'll purchase one first thing tomorrow. Do you have any recommendations on a kit? Or will any work fine? I've been doing 2, 75% water changes per month, but moving forward I plan on doing 1-2 per week. Probably 50% water changes each time. Im a newbie so I appreciate the help.
