thinking about picking up a Bichir eel to add to my tank with my Oscar and I was just wondering if anyone knew if the two would get along or if I would be asking for trouble.
This. Though the potential for predation is also a major concern, regardless of the oscar's general temperament. Since you use the name "bichir eel," I assume you're most likely referring to Polypterus senegalus, which grow quite slowly, with growth in captive bred specimens often coming to a near standstill once they reach 7-9 inches. So even if the oscar is small now, it could potentially outgrow the bichir to the point of seeing it as prey. If it's an adult oscar, you definitely won't be able to keep them together unless you either get the bichir at adult size or grow it out yourself.go ask the oscar
It really depends on the fish, some get along some just dont...
rearrange the tank before putting the bichir to (hopefully ) remove any territories extablished by the oscar
+1You might want to upgrade your tank before even thinking about adding any bichirs

Most people would jump down your throat at keeping a 12" fish in a tank that has the width/depth of 12.5". While it is surviving, its quality of life is greatly diminished.My tank is a 55 gallon and my Oscar Is at least 12", but he hasn't been a very aggressive fish.
