I want to add some blue to my 375g tank. It has the following inhabitants: 14" Arowanna, two 8" motoro stingrays, five 7" red severums. I was thinking about adding two or three blue fish that would be 6-8" (out of eating range for the aro, who is a chicken anyways). I want a peaceful, colorful fish that grows to 10-12". So far I have come up with the Brasiliensis Geo and Jack Dempseys. Is there any other species I am over looking? What you you guys think?
