One of my africans is sick i think. I have six small africans in a 55 gallon and one is swimming vertical with her head pointed toward the bottom of the tank beside the aquarium intake. Usually they all go crazy when i feed them but she has not eaten for a day. She looks like she is struggling when she is swimming. This tank has only been running for a week and i have been using cycle to help speed up the process. the ammonia reading is 1.5 . I have been doing small water changes to help.
