pet shark

Question
i have a small pet shark in a tank with other fish.. hes very small though.. but he has like three tumor like things on his body.. ones under his mouth and the other two are on his tail.. they werent there yesterday and they are weird.. they look like bubbles.. whats wrong and will it hurt my other fish?

Answer
Hi Jamie,
  Are you sure that they aren't air bubbles?  If they were air bubbles, they will likely be gone by now. If they aren't, then they are some sort of parasite, and that would be a bad thing.
