You guys! I feel like a gosh dang parent!
You have to be nice, I know personally when I see a fish say, at petco, Its either buy it now or wait a month or so.
I dont get the chance to go to any pet shop very often, and when I do its because I've got a fish in mind, or because we were close to one while we were already out, so I got to run in.
I know I certianly didn't plan out my 55G, but its worked out great so far.
I tried planning it out, but, lets face it.
Its much easier to see the fish you want in real life before you plan the whole tank out.
Its hard running back and forth from the pet shops, especially when you cant drive, and you live in the middle of suburbia.
My point is you can't get mad at someone because they didn't do it your way.
