If you are wondering about water parameters, temperature tolerance, and temperament, then I would say "Yes" They are relatively easy to take care of. As for a "Beginning Monster"...they are all on the higher level status

If you've got a big tank with plenty of well-established filtration then they're pretty easy to keep, you've just got to be in it for the long-haul, which I wasn't when I bought mine as I was still living at home and two years later I sold it and the tank as it had nearly out-grown the 150g and I was going flatting and couldn't justify a bigger tank for it. Still kicking myself to this day as I've never seen another for sale since I sold mine...

A pacu is in no way whatsoever a good beginners monster fish, yes they are hardy but they do get to 42'' and are deep bodied, you would require a massive tank along the lines of 10x4 minimum or better still, a pond. Aros all get large but are slender bodied fish that are for the most part flexible, and you could get away with keeping one of the smaller species, say a Jardini in a 180 for life. To the original poster, I would highly recommend arowanas as a beginners monster fish providing you can provide a decent size tank with good water quality.kpax632;2478011; said:a pacu would be better but arrows need atleast a 200 to grow full length
