Do you remember the show MythBusters? The show was where scientists would try to prove whether a myth was real. I used to love this show as a kid, and I loved seeing all the crazy experiments the people on the show would do. I wonder what your favorite reefing myths are and if they have been busted. If they have not been busted, maybe someone can prove if they are true or not.

  • Moorish Idols need to be kept in a group to survive
  • Rock Beauty needs a sponge diet
  • ich comes from toilet seats
  • mandarin fish can’t be maintained on commercial food

Ich comes from toilet seats? Now, that is one that I have never heard of.

What if it isn't growing but still looks healthy? It's an interesting thought, for sure!

I might be inclined to add ammonia toxicity to the list. It is much less toxic than most reefers think because so much of the new aquarist literature focuses on minimizing ammonia.

IMO, that focus has likely hurt the hobby.
