Over the last 2 days it seems that my copepods have all disappeared. Water parameters are good, I do have a small population of flatworms that are siphoned out regularly. They are not an issue yet. Have a clown and 1.5 inch yellow tang. Zoes and mushrooms and feather duster. Could there be something else that I cannot test for? Water change was done 2 weeks ago, another one later today. Any suggestions or answers would be great.
