I'm just curious if you individuals with 220-300 gallon tanks are satisfied, or do you still want bigger? I'm just curious, because I don't want to buy a large tank to only want bigger later on. I bought a 40 gallon wanted bigger, then went to a 55, next a 125, and now I want 200+ gallons. I'm hoping that if I get into a 200+ gallon tank i will be happy and not want to upgrade? Let me know what you think.
