I have a pleco already. Does anyone have any suggestions for tank mates with an gold Australian arowana?
1)your 180 is pretty much going to only fit your jar when its fully grown. Even one more grown silver or black wont fit in it. Pacu or a RTC might be a good idea. If you use common sense you would not have even suggested a piranhamfk4life;2617475; said:its a jar it has mainly gold coloration with blue on its fins. well i have the arowana in his own 55 gallon right now and i am transferring to a 125 or 180 gallon after he hits 5 inches or 6 inches.i got a suggestion for tank mates at a fish store with very large aggressive fish. They told me 2 to 1 silver aros over austrilian aros because austrilian aros are very aggressive towards other fish. and any catfish would be fine and plecos of course. they pretty much told me if it can't fit in it's mouth you will be okay.
I know these fish probably do not mix and it has not been attempted but what do you guys think about an austrilian arowana and here are two ideas im thinking about.
1) two silver arows or black arrows, a red tail cat, pleco or plecos and maybe a pacu or piranhas. just throwing some ideas out there. obviously i do not want the fish to kill one another. Just let me know what you guys think.
2) an goliath african tiger fish, a ray or some other bottom feeder maybe an aba knife.
3) honestly i am thinking about having fish at the top, middle, and bottom, any suggestions I would love to hear them. I already have the austrilian arowana and a pleco.

. A ray would be ripped to shreds by your jar.
