As a beginner, do you think the care for either the tiger oscar or the silver arowana is too demanding? What are the care requirements? Key questions:
Ph level?
Temperature?
Feeding?
Tank mates?
Size from baby to adult?
I am also researching some of these care tips on other websites but I always post questions to forums to get some personal, hands-on suggestions that owners have. Any and all tips/suggestions are welcome and encouraged. Thanks in advance for all info!
