All the fish stores are wrong then.....Keeping more than one in a big tank can possibly be risky let alone as many as you have in a small tank....And the Magnificent worries me....He is gonna die if thats what he is as they need VERY strong flow and very high light...they will perch themselves on a rock directly under a 400 watt halide..Stick with the bubble tips..They would be okay in your system but your gonna have to get rid of the rest. And if they walk into a powerhead or die when you are not home they can kill your entire tank.
