I forgot to mention that I went to the mall with my friends and stopped by Petsmart. Now, I will be going to a place called Selmer's Petland for my fish, but I thought I'd take a look while near Petsmart. I was looking around and asked someone about the seed material. The lady said, "All of our fish representatives are busy at the moment." So I was just like..."Can I just get some of the gravel from one of your tanks because I am doing something called cycling and it'd help me out." Lady:"I don't think we're allowed to do that." So, I just said alright and walked away to go look at fish. I don't know where the hell all the "fish reps" were but whatever. I didn't even know that Petsmart had fish representatives. When I was looking at the fish, I saw a few that I liked. Selmer's has a larger selection, but I found a few that I definitely want. I am unsure about compatibility, so that is where all of you come in to help me out.
**Edit, made a new thread about the fish.
