Hi everyone :)
Last year my partner and I bought a little betta fish for his mother who is slightly disabled and suffers fatigue. She named him Happy, and she really loves him but she can't take care of him anymore so she gave him back to us last week (9 days ago exactly).
Happy has never been an overly active fish. I know she had a lot of trouble getting the PH right etc. We've spent the last week getting the PH down to 7.0/7.2 from about 7.8. I've also just now added a small heater to get the temperature up to 27C (about 80F).
Because he's never been active (I think because his conditions have never been quite right) and has always just sat down the bottom of his bowl, I've only just this morning discovered this:
(Sorry for the size, I was hoping to show detail)
Is that fin rot? or damage from the plastic plants (I'll be replacing this afternoon...) I also wanted to check that the red spot on his head looks like normal colouration and not a bacterial thing? Not having had him since he was a little tyke I don't know what's normal for him :(
I have added API's Bettafix and PimaFix (which my partners mum gave to us with Happy) to the water per the instructions, though I've read mixed reviews on the net; a lot of people who don't know much like me say it worked for their Betta fish fin rot etc, but I've read in several places API doesn't test their products properly for adverse reactions, PimaFix contains clove oil and no actual anti-fungals and so is more of an anaethetic. Should I look into other medication alternatives if this is fin rot? (If it isn't I'm obviously not going to continue any treatments)
He is in a 12L tank (2.75gallons) with an airstone but no filter. He had a 100% water change 9 days ago and I did a 25% water change 5 days ago when bringing the PH down.. He hasn't been eating.
Temp: 27C/80F but only as of about an hour ago.
I used aquarium salts and Seachem Prime dechlorinator for all water changes. I used Seachem Neutral Regulator initially to bring the PH down but our water is ridiculously high KH and GH, so we used Seachem Discuss buffer and Neutral Regulator in tandem to reach 7.0. This was over a course of 7 days. We followed all the instructions.
Please any advice or opinions would be greatly appreciated.
