This is the best photo I could get.. I first saw them and thought look my pods multiplied.. Then wow these are tiny white guys everywhere... It's probably Ich..
I lost a fish probably 3 days ago and around that time added a mesh around my return pump (which has been sitting out of water for a long time but use to be used in freshwater) before that maybe a week ago I added chaeto which use to be from someone else's tank. Other than that nothing new.
What could have caused this? Maybe I overdosed my calcium and my only fish stressed out and now I have an Ich outbreak? Thanks
