stressed

My Arowana (width 2 inch, length 8 inch) ate baby fish (live feed) and acted weird first 2 days (Tuesday and Wednesday) and after that since past Thursday is sitting at the bottom of the tank and still swimming slanted. It felt like getting better on Sunday and Monday as it was actively swimming...

My 5” Tiger Oscar tried to eat my 5” Silver Arowana. This is my first Arowana so I’m looking for advice from experienced keepers on treatment. They were in a 125g but I have since separated the Arowana to a 75g by himself. The pellets are from trying to get him to eat.
