I picked up a Jack Demsey and Tiger Oscar yesterday evening. Their both about an inch and a half. I bought them from petco and really do not trust their fish. The prices were too good though. Both fish are currently in a qt 30 gallon tank with prazi and salt. Temp is 82 degrees with a Emperor 280. As you'll be able to see in the pictures they seem to hide in the back fright corner. I've broken up an algae wafer and through in a couple of black worms. I also put a couple of small flakes into the tank. I through a couple of pellets in last night and took them out 30 minutes later. I was planning on putting the Jack Demsey in my 130 gallon tank with my aro and stingrays. At first I had thought about putting the oscar in there as well but I'm worried about the ray's eyes. I'll more then likely get a 75-90 gallon tank just for the oscar.
