Post got deleted double post. Has anyone in Cichlids area with Discus and Farlowellas had any problems with them (Farlo's) dieing in their tanks? If so, what have you done to resolve the problem if not what could be my problem? Water para. good, temp just dropped from 83 to 80F. Have 3 Discus, "1" Farlowella left, 6 Black Neon Tetras, and 4 Cardinal Tetras- all doing well except Farlos: very concerned.:help:
