Has anyone shopped at Walmart for fish and had sucess? I have avoided Walmart like the plague in the past but i just recently had a friend that bought a few tetras from there and they seem to be doing fine, not that they can't go downhill fast, but its been about a week. She said that they have a 90 day return policy! thats crazy! and they are pretty cheap. I was thinking about picking up a few more danios for my 35 gal and was thinking about trying them out but im kinda nervous about getting any diseases they may have and if it spreads through my tank i dont want to lose any of my babies. What do you guys think, have you ever had any sucess with them? do you think i should try them out?
