Hi I have a Ctenopoma acutirostre that is just over a year old and for the past few days she hasn't been acting normal. Her swimming seems to be slowed down appearing sluggish and something doesn't seem right with the upper rear part of the tail area while swimming. She has also been sitting at the bottom of the tank not moving as much. Usually my fish is very active. She has been eating however. I have a 55 gallon tank, with the temperature and water quality at an ideal level. There seems to be nothing wrong with appearance, besides some color has faded by the mouth. I am not sure if I am looking to far into this and exaggerating a little with that due to worrying. Any help would be nice thank!
