Thanks Cyclop,
I was originally looking to get a 55g and then I saw how deep they were, I decided I wanted to get a 75g and then I found the 125g for 75$ usd so I jumped on it. I didnt know what kind of fish I wanted untill recently when I started reading about Oscars and how much peronality they had.
I have been thinking about putting some plexi glass in between the light and the water, I'm still working on how I could put it in the canopy and still be able to feed the fish. I dont want to pick the canopy up and then pick up a sheet of plexi glass. I was thinking of maybe adding little doors on the front of my canopy. As far as the windex, I'll make sure I clean the tank out really well. I plan on letting everything run for a week before I put Oscars in it.
