I was at the BIGGEST lfs in my area the other day and decided to pick up some feeders as a treat for my fish who rarely ever get them. The guy I asked goes in a back room and then comes back with a bag full of blue water and goldfish. I asked him why the water was blue and he said that it stops the goldfish from getting diseases etc so they cant give anything to my fish...
Could this be true? Or just a marketing scheme?
