Ugggh!!!! 120 GALLONS?!?! I've been considering getting out of the fish hobby too. But I think this actually re-inspired me and reminded me how much I love my tanks. They are a lot of work, and Oscars are messy fish, so even more work than most freshwater fish. However, I love the tranquility of the tanks. I got this pair of Oscars as babies about an inch long and they're coming up on 3 years and are family at this point. They've both battled some illnesses right from the start, but they're troopers!! They're both around 10 inches now and doing well. They seem to love the new 75 gallon with the added depth. I didn't realize how big my PECO was either til I had to move him, he's a BEAST!!!
