Do betta's need real plants or do they just prefer them? I have a cycling 20-30gallon hexagon tankthat im trying to think of what to add in it. My girlfriend wants me to put in her 2 goldfish in. And ive been thinking about a betta, or dwarf puffers. I really wanna stay away from real plants since im doing that in my 55gallon and i already have plastic plants that i would rather use then throw away or leave laying around.
