I stopped by Slither and Swim last week, and bought a young angelfish. He's really healthy and I'm considering another drive to pick up another one. I did notice a few tanks with other fish seemed to have a few fish with fin and tail rot, but maybe they were just getting nipped by their tankmates. One thing I liked about the store, each tank had individual filtration, so if some fish in one tank have parasites or whatever it wouldn't spread throughout all the tanks. Overall the fish were much healthier than those you'd find in Petco or Petsmart.
