So as storm Nemo started my black ghost knife started acting weird. She normally came out for feeding time and didn't. My first sign something was wrong. Next, a couple hours later she wasn't in her normal hallow log. She was in a very tight area between rocks. So this morning I woke up and found her alive, on her side kinda on deaths door, her anal fin shredded, grey coloring behind her gills and heavily breathing. I have had her since November 17th and she was doing really well since this incident. So what changed in the tank was i got a moon light gourami and a male blue paradise(rescue from school, i go to an aquaculture high school) Tank is a 29 gallon, with red dwarf gourami, moonlight gourami, two cory cats(emerald and long fin) and a hujeta gar. Yes ik that the ghost knife currently 4 1/2" inches will have to go to a bigger tank. Currently cycling a 75 gallon for her. So can you tell what wrong with her. To recap her anal fin is shredded, grey around the gills, tail fin is reddish(bleeding like) and is curved on her side like she is dead. Tomorrow will be my chance to go to a store to get supplies Everything had been closed because of Nemo and has had terrible timing so is their anything i can do or? She is currently in her own tank(10 gallon bow front, 50% water from old tank other new). Anything would help thank you. Also test kit is on list to get, ran out last week so i can't tell you levels of anything.
because i had researched that they can be aggressive at times. Although he is extremly reclusive and sits behind the filter 90% of the time.
