Thanks for the help. Not sure what kind of fish they are, but they are decent sized, maybe a tang or trigger, but I'm not that versed in salt water fish. Yeah, the more I think about it now I want sand instead of gravel. I go back and forth. lol I got some samples from the quarry that look nice, but the more I see tanks with sand they just seem to look cleaner/more natural. Gravel is starting to look very pet shopish to me now. Where do you get pool filter sand? Pool store? Or just HD or Menards?
