Saroon Posted January 11, 2012 Share Posted January 11, 2012 As the title says i havenoticed that a number of my electric yellows and Acei have developed a black spot on the edge of their gill plates. Not all of them have it, and Im just curious as to what that black spot means exactly. Does anyone have any idea?They behave normally, but i have noticed that they are still skittish when a person approaches the tank. They have only been in the tank just under a week. any help would be appreciated.Josh Link to comment Share on other sites More sharing options...
malawi sand diver Posted January 16, 2012 Share Posted January 16, 2012 Hi Josh, is it possible to get a pic of the black spots? I have read that a lot of spiralina causes these but there is no evidence. Sometimes they are just natural pigmentation. Another possibility is that they are some sort of parasite if they have been in with fish from a pond for example. Link to comment Share on other sites More sharing options...
