I understand what you meant and I didn't mean to come off as being snippy, sorry if I came off that way. I just figured she would look at the angels, look at the mollies and think nope, not gonna fit, but I guess not. I actually got a chuckle out of it. I just wish they gave them a little common sense training, like don't put angelfish in a 10, or don't add 7 fish at once, instead of that fish is semi aggressive so it can't go in the tank with community fish. One lady there knows her stuff, but most don't know much more about the fish than their names.Exactly. Could is not an absolute. Therefore don't assume that Angels and Mollies can't get along in the same tank. 2 of my 3 tanks eat live feeders 1-2x a week. One tank has small mouths that need small food. An average Molly would be safe in that tank. My big tank has a big mouth in it. A Molly would be toast. Every tank is different and the dynamics in each tank are different. The Petsmart lady is basing her "expertise" on a chart. Petco has a similar chart. I haven't referenced it in years because each situation is different. That's all I'm saying.
