I have a Bagarius yarrelli 'India' i got from Wes a while ago and I was wondering how hot to keep the tank because i was hearing how when they get large they like cold water. Also i was wondering if they will require a powerhead when they get larger. It is currently 8" and in a 75 gallon rubbermaid tub at 78 degrees fahrenheit. It does not have current but it has a Magnum 350 canister filter going into bioballs and then entering the tank. Thanks!
