Did you ever know why pet store fish always seem to be sick?

I never knew how they filtered, but that makes a ton of sense!! WOW! haha They must put some kind of medication in the water to prevent any disease though IMO because i'm sure they cant afford to lose all their tanks if one fish comes in with disease. Well, they probably could afford it, but I think they'd chose to prevent over letting it happen.

Mine gives aquarium salt to salt tolerant fish.
