Hey guys, so my new 225 is up and ready. It has been cycling for about 3 months. Currently I have my 2 6-8 inch Oscars in it with a african catfish and a jack dempsey. I have been raising my silver Arowana for a few months now and he is about 7-9 inches. Is it safe for him to be put in the big tank with the Oscars now, or should I continue to wait?
