Do people keep silver and black aros in the same tank together? I currently have a 14" silver in a 90 gallon tank (48x18x24). Im going to keep him in there for about a year and a half, maybe two, until I get a bigger tank, probably somewhere in the 4-500 gallon range, plus sump, depending on some things. Anyone think I could get another black and put it in the 90? Probably should wait until I get the bigger tank, huh? Just lookin for some feedback.
