It's incredible hard to be sure ick is in the tank.
But when I walked into AG's freshwater section the very first tank had numerous fish clearly coated in white spots, and upon closer inspection they looked like little granules of salt stuck to the fish.
This is what I've have been told to look for as an outbreak of ick in a tank.
And they had one fish laying in that tank on it's side with granules falling off of him.
I understand that fish get sick, and tanks get infections, but that clearly infected tank was the only infected one, which was labeled not for sale, hopefully for treatment.
I truly hope that AG improves, and I'd love to give them some business to make sure it happens, but I won't get livestock from them till I see the improvements.
And also Quarantine! it's important whether it's 1.99 guppies or 199. Discus!
Each generation imagines itself to be more intelligent than the one that went before it, and wiser than the one that comes after it.
It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.
