zero nitrate? im not calling you a liar but thats almost unheard of unless you've done a 100% water change and if you did id expect that to be the killer. unless the tank is brand new and you have lierally filled it up and began a cycle
Joe, hmmm.. that could be it, but again, everytime i feed, i throw in about 30-40 feeders.. and i am sorry, correction on nitrate.. the nitrate is at 30ppm.. I was so used to saltwater and typing 0ppm.. but again, it may be internal parasite because when i pick up the fish.. there were brown gooey stuffs coming out of their mouth.. so i expected it to be internally.
