Thanks. Good answer and it follows what I have been reading on the internet. I need a bigger tank too. Maybe 20 gallons.
Just get a big tank, some cichlids and call it a day. My wife's cousin recently had to upgrade to a 500 gallon tank. They got the cichlids from her brother over 15 years ago. They are huge!!
Not to mention weight-sensitive! A gallon of water weighs about 8.3 pounds so a 500 gallon aquarium would weigh around 2 tons concentrated in a relatively small area. It's not something you want to put on a second-story floor!500 gallons? Dayumn! I just wanted to introduce my 8 year old to fish. This is quickly getting expensive, time consuming and space sensitive.
