I have a 10gal tank that houses a plecto, and 2 Convict Cichlids (1 male, 1 female). I have had the tank for 4 years with no problems but about a week before Thanksgiving I cleaned the gravel (50% water change) and changed the filter. (Nothing different than usual).
About 2 days later I noticed my female swimming sideways. I took a water sample to the fish store and found that my ammonia level was very high (2.0). Began doing 50% water changes every other day, per store recommendation. Then on Thanksgiving day I found an infestation of worms in my tank, panicked and completely cleaned and sterilized the tank (boiled rocks, put tank into dishwasher without soap, new filter, etc) and began my cycle all over again. At this point female was still swimming sideways but was showing herself daily.
Day after Thanksgiving purchased live bacteria and med "Pipzine" for parasites, which is what the fish store thought my female's problem was. I was told to do 25% water changes every other day. But because I still had high ammonia and couldn't remove the filter while treating with Pipzine (best result recommendation). I was in a catch 22 so fish store told me to stop using the Pipzine (I had done 2 doses) and to just continue to do 25% water changes every other day.
It took about 5 days to get the tank to level out (natural biofilter), waited a couple more days (to see if there were any changes in her behavior) and then went to fish store again for more recommendations as my female was now not showing herself, but hiding in her cave and usually just leaning sideways or upside down at the top (can see her through the hole), which she is still doing.
When I tap on the tank stand (as I do when I feed them), she would move for me but wouldn't come out. I was then told to treat with Melifix for 7 days for bacteria. I have done this and today is day 7.
Female came out of cave for me last night (first time in over a week) but struggled to eat, swam sideways, and floated at the top upside down. I called the fish store to tell them that it doesn't seem to be working. Fish store tells me that the bacteria probably got into her swim bladder and that she will die and that I can give her a painless death by putting her in a bowl of water with clove oil.
I don't want her to die so I am asking if any of you have any recommendations for me besides killing her or waiting for her to die. Is there ANYTHING else I can do?
Thank you,
Steph
