I absolutely love the looks of a well planted tank. I found it much cheaper to buy plants on line than to go to the pet store.
IMO, the bigger the tank, the easier it is to maintain. Water quality does not yo-yo as much.
Everyone's tanks look so great, especially that coral reef tank my goodness *-*
I used to have a 10 gallon with a beta and cherry shrimp, but it's actually quite a bit of maintenance to keep up a fish tank properly. Between college and moving, they had to be given up
My ultimate dream would be a 300 gallon with a quad of albino tiger oscars - preferably veiltail varieties. Oscars are absolutely my favorite fish, they're so cool.
