Neha Posted September 19, 2022 Share Posted September 19, 2022 (edited) I have a half-moon betta, his name is Frodo. He lives in a 10 gallon planted tank. He has had a setup change from a 5 gallon tank. His tank setup is currently new and lightly planted. Below are tank parameters: Ammonia: 0 Nitrates: 10 Nitrites: 0 ph: 7.6-8 gh: 300 kh: 120 Temp: 78 I've attached a picture of his current fin rot situation which I'm currently treating with salt as I've done two other times. So here's the problem: I have had him for a year and this is the third time he is suffering from fin rot. The first time and the second time happened when I was not at home, so I couldn't figure out the cause. The second time he had a chunk missing from his tail and looked like he had been biting it off. At the time he did not have any tank mates so I associated the cause to be his loneliness. I added 12 pygmy corydoras which seemed to solve the problem until this happened. He lived alone in a planted (not so balanced) 5 gallon for three months and was doing great. I set up his 10 gallon about 1.5 weeks ago and he developed a fin rot 4 days ago. This time it does not look like he has been biting his fins, it looks like his fin has been burnt just like a paper. Now the change in water parameters from his previous dwelling to this 10 gallon has been in terms of gh, kh, and ph. After his 5 gallon he lived in store bought spring water/drinking water for a few days since we were traveling. Could the change in these parameters have caused a fin rot? Or is it because he is lonely in his 10 gallon and hence could be having stress? Please let me know what you think. As always, grateful to be a part of this awesome group!
