Hi. I have a 46g with 2 smaller frontosas, 3 silver pictus, 1 green pictus, 1 spotted raphael and a small feeder goldfish (he looked cool, never seen a feeder like him before and no I dont use feeders lol.) My water is alright but could be better. I have a marineland penquin 200 and an Acquaclear 70. I was thinking about putting the big AC-110 on there. I have an AC-110 on my 125 and love it. Im just wondering if theres going to be to much current for the guys. All of them are generally 3-4in. Thanks.
