I bought my first Dat about a week ago and I'm in love with them. I usually go for all catfish, but I wanna try a Dat community. I bought a second Dat and I'm seeing some serious aggression. My larger dat aroun 4" is givin my new dat 3" a hard time chasing him all over the tank. Is this normal I thought dat's are peaceful just predatory. Also I bought a Frontosa and 3 Uaru's I was wondering will these guy's work in a tank together. They all get fairly big and as far as I know are peaceable. Also is it possible to breed these fish in such a community. Another question is I've heard you can tell widebars from indo's by physical characteristics other than theyre bars. What are the physical differences?, and lastly where can I get some rarer dats like widebar and thinbar? My first post didn't net many reponses hopefully this one will get more. I truly love this monster fish and just want to know as much as I can about them so I can successfully keep them. Thanx to all who reply in advance.
