Our industry loves to have rules of thumb based on how much water you have in your tank. Everything from percentages of water for a water change, to how big of a tank you can have for your fish. My question to you is this- do you go by actual water volume in the tank, or what the tank can hold?
For example, I have a 30 gallon tank, but in reality with the equipment, rocks, sand, etc. it has closer to 20 gallons of water actually inside it. That being said, if you were religiously sticking to 10% water changes every week, would you do 3 gallons (tanks total volume) or 2 gallons (water actually in the tank).
Same goes for fish, in my situation of a 30 gallon tank, would you put fish in that are good in a 30 gallon tank, or would you stick with smaller fish that are best suited for 20?
I have my personal opinion and will reveal that later, I just want to see what all you guys think!
