Hii I just got back into the hobby after a long time and I have a question I bought a 100 gallon stock tank I plan to put a Oscar in but I have a few questions?Is it to put two Oscar’s in there ? What type of heating can I use inside the stock tank it’s a 100 gallon Rubbermaid? Finally is there any good bottom dwelling fish that won’t out grow the 100 gallon ? Thank you and sorry if this isn’t the write spot to post this just joined and figured this is the right group of people that could answer my questions
