A few random Arowana questions from new owner

  • We are currently upgrading MFK. thanks! -neo
Is there any tankmates in there with it? it doesnt look like tail rot to me....
 
Just a 5" common pleco and some rosy red feeders.

There was a 6" Chocolate for 1 day that may have done it. It hasn't gotten any worse but only a little better and he seems a little bigger as well. Eating good too.
