Nice to meet you sirYes silver arowana 10 inch
Yes silver arowana 10 inch
3to 4 weeksPossibly the larger Silver Arowana attacked the smaller Redtail Catfish.
How long have the Arowana and Redtail been together?
3to 4 weeks
Can i give a hidden place to a rtc because i havent a separate tankYou may need to separate. The fin looks like it was ripped off. Observe the aquarium for awhile and see what Arowana does when the Redtail Catfish goes up for food. The attacks can also be happening at night.
And i gave them foods separately .hand feeding to rtc (shrimp ) pellets for arowana (food stick & arg )The difference between fin rot and a bite from another fish is the shape of the injury. When there is fin rot, there won't be such an acute breakage in the fin as shown in your picture. However, when a fin is bitten, you will usually see an acute breakage in the fin.
