I feel so bad for the fish, when ever I walk past the small tanks at Walmart. My store here on Maui still sells fish. Most of them are dead or dying when I see them. I did buy a Betta, that ended up living for a decent amount of time. I don't think I would bother with buying any of the other types of fish they sell. I have also seen some plants in the tanks, for sale. But again none of them look healthy. I wonder if there is anything someone can do to help revive these fish, before they completely die. If you were to buy a fish from walmart, that was obviously sick, would there be anyway to bring it back to a healthier state? Would it be worth the hassle?
