I am planning on picking up five or six juvie wild caught Uaru's from a lfs in Jersey that have for only $8.99. They are supposed to be around 1 1/2-2". I will be adding them to my 180 SA tank. I have been doing some research about Uaru's online and I see mixed comments as to whether they are difficult to raise or not. Some say they are extremely difficult and some say only moderate. Can I get any comments/suggestions and pic's of Uaru's?
