I saw some puffers just like that yesterday for the first time, But in the freshwater section?! I was amazed there was a really cool freshwater fish. I was in the freshwater section cause one of my friends wanted to start a tank like mine, but not go saltwater....
Oh and to make this on topic again, I only lose about 1/4 gallon a day if not less. But I'll get some random days when I'll lose 3/4 a gallon and my pumps half out of the water... todays my day off, im gunna go build that ATO that Biff directed me to build!
