I got my 120G tank home yesterday and I ended up with a 75G as well that I am going to set up at my grandmothers house. She said she would like some live plants. What are the hardiest plants and community fish I can put in this tank? She isn't picky about the fish. If you had to set up a tank for an elderly person give me your list of fish that you would stock the 75G with. I know I can't put them all in at once but what is the hardiest group of community fish that will get along. Also are there any fool proof live plants that I can get and not have to buy some super expensive lights. I can stop in and do some water changes but she is afraid she is going to have to constantly look over the tank and I want her to just enjoy watching it.
