Frequently Asked Questions
Can Oscars live with other fish?
Oscars are territorial and may show aggression towards smaller tankmates. Compatible tankmates should be large and robust, with similar water parameter requirements.
Do Oscars need a lot of maintenance?
Yes, because of their size, messy eating habits, and heavy waste production, Oscars do require careful tank upkeep. Their health and wellbeing depend on regular filtration and water changes.
How often should Oscars be fed?
To avoid overfeeding and preserve the quality of the water, Oscars should only be fed two or three times a day, and only as much as they can finish in a few minutes.
