75 Gallon Tank With an Oscar and a Bullhead Catfish

  • We are currently upgrading MFK. thanks! -neo
The average info you get telling you a tank is large enough for many fish is total BS, as are the specs for enough filtration.
Putting an oscar in a 55 gal, is like putting a Great Dane in a bathroom, 24/7.
And if you change the water once per week, its like only cleaning out the dog doo once per week.
 
Madtoms (Noturus), that many people call bullheads, range from 3" to 1', depending on the species. True bullheads (Ameiurus), grow from 1' to 3'+ depending on the species, so before I'd consider tankmates, I'd try to find out what kind of catfish I had.

Rock Bass are cool, and would fit in a 75. They can change colors like chameleons, almost.
