Hi, I'm new to the forums. I thought I'd share a couple pictures of my tank. It's a 77 gal. It doesn't quite look this nice anymore though, it seems to have developed and algae problem
that's why I'm here to try, to research how I can fix it. This was taken about 6 weeks ago.

I have 3 of them in there, and they all still have eyeballs.
I don't think they'd attempt to go near Oscar, or they'd be lunch. If they start to pick on the 2 pleco's, they'll have to go but they are considerably smaller so I haven't noticed anything there either.
