Hi all, just picked up a Craigslist rescue. Two Oscars (8/9 yrs old) that his ex wife left. They came with a 75g tank/ stand and a big two chamber HOB filter. Both are definitely well fed, but lack of maintinance taken it's toll. Ripped scales, some small infections, and dull colors. The gravel had so much built up muck it turned the tank black when moving things. Looking for my best course of action. As of this evening they are set up with the cycled media with bare bottom and a small bubbler. Tia for any and all advice as this is new to me.
