There is not a day that goes by where I look into my tanks and see something new. It's absolutely fascinating and while there are a lot of bads, it is a never ending learning process, and that's part of the fun. It never gets stagnant there is always something new to learn. Just the other day I found a 1 inch limpet in my newer tank and I have no idea how something that big went undetected for so long, but cool as heck.
