would a 4" armatus be okay in a 40 breeder for a little while, or should I put it in a 75? It will be all by itself. I've been wanting an armatus for quite a while, but one came up that I didn't plan on, so I had to get i, so I'm just trying to figure out where to put it. Will a AquaClear 70 powerhead be okay to use in the 40 for it?
