Hello there!
I have a long story that I will try to keep short. My sister just moved out of her house after 10+ years. As she was leaving the house I insisted that she take her 9 year old Fantail Goldfish. She had him in a 20-25 gallon tank with a rather large plecostamus. We transferred "Peanut Butter" in a bucket for the journey to his new home. We put him in the same tank once we got to the new house. She wasn't sure that she wanted to deal with the fish and everything else going on in her life at this time.
However, after several days watching him in this tank where the water was terribly cloudy and he looked very labored in his breathing I decided to set up my 45 gallon tank and invite him to come and live with me. We sold the pleco back to the fish store, he was attacking PB way too often.
I went to a very knowledgeable place that specializes in fish and got all things needed to set PB up in his new home. I got the live bacteria (bio-spira) and let the water set for 24 hours before acclimating PB to his new home. He seemed thrilled and excited to be in such a large space for about 2-3 days. Then he began to simply sit on the bottom of the tank in a corner and not move unless being fed. His eyes began to get cloudy and he just seemed miserable.
I feed him the flakes as well as the pellets. He is a very large fish, maybe the length of a hand not including his tail. He is very round and I would guess at least 6 inches without his tail. You need two hands to pick him up!
I give him 8 pellets plus a little tiny pinch of the flakes. My sister said that he doesn't like the pellets and feels guilty so she gives him the flakes as well.
I took the water into the store and had them test it. They told me that the ammonia was really high so I came home and did a 25% water change. I also bought a testing kit to be able to check the tank more often by myself. This morning this is the results
based on my own testing...
Nitrite level: between 8-10
Ammonia level: at least a 1.5 maybe a 2 but the color was like Kermit the frog green (dangerous- right?)
The PH was 7 -7.5
The GH was an 8-10 and
The KH was a -1
I know the ammonia is bad and the fact that the KH (carbonate?) reading was a negative (where the water never was blue turning to yellow, it was just constantly yellow) ....I am not sure what to do?
The time frame on all of this is rather short so....what is wrong?
Time Frame:
New Tank set-up Saturday the 7th.
Bio-Filter, Rectangle Tank, conditioned the water....
PB released into the new tank Sunday the 8th.
Completely empty tank, just the fish.
Water checked and 25% changed on the 12th - Thursday.
Used "prime" to clean the new water and added some salt to match the
new water measurements. I added some driftwood, a live plant, two
plastics plants and I tried to feed him a pea which he had no interest in.
Re-checked and still a problem - Today the 17th....
See the test results above....
I am not sure what to do and I feel terrible that he isn't enjoying his new tank because the ammonia content is burning his gills and lungs...he doesn't look happy....
HELP!
What else do you need to know from me to help solve this problem?
