Angelo as a healthy Youngin:
I am very sad to say that I was a bad betta owner. Maybe I was just uninformed, but ignorance is no excuse.
I purchased my betta approximately 6 months ago. He lives in a small bowl (<1gal) with rocks and a fake plant. He was entirely white, save a few specks, with a full and healthy tail. Over time his tail began to become more ragged. I did not know about fin rot, and simply thought that this was part of betta maturation. At the time I was doing a full water change about once per week. I now know this to be insufficient to sustain a clean environment. Appr 1 month ago, a friend of mine pointed out what he knew to be "Fin Rot" and I started treatment with Bettafix (also now know this to be no good) and AQ salts.
The rot seemed to slow with the treatment (1 wk), but the weather was getting colder, and so was Angelo's water (65-68F). I purchased a very small 7.5W heater "pre set" specifically for bettas. I placed angelo in a larger 1 gal vase with the heater to slowly bring the water up to temp. I came back the next morning to the horror of finding angelo floating, without movement at the top of the tank. I checked the water temperature - 95 degrees! ARGHHH. I cursed myself for not experimenting with the heater, but I was desperate to save my poor fish and in doing so had probably killed him! His breathing appeared very difficult, possibly because of the DO at 95 degrees...Possibly because I had just fried his brain. I took the heater out and allowed the water to slowly approach room temperature.
1 day passed... still floating with labored breathing... won't eat food, eyes don't appear to be moving much. 3 days pass and he still floats, refusing to eat. Occasionally he tries to swim to the bottom, but floats right back up to the top.
I visit my girl on the weekends, and will have to leave Angelo for 2 days... I place him back in his old habitat where he was happy, assuming it will be a hospice stay. He wedges himself between two rocks at the bottom, tail pointed towards the top of the tank. Breathing is still very labored. I can't bear to look at him.
To make his home a little warmer I placed the heater in glass of water and wrapped a towel around both, keeping it fairly dark and ~75 degrees. He still won't eat, so I do one last water change and head out.
Monday afternoon I slowly approach what I though was surely my poor fish's coffin. I lift a corner of the towel and see frantic movement. Happy movement! He was alive! I was so happy I took the bowl out into the light of the room to look him over... Was this even my fish? His coat had changed colors dramatically... It had turned quite black. in his sickness, the rot had returned and claimed much of his rear fin and I wondered if it had started to ravage his body.
I immediately fed him some brine which he gobbled up. Then I dosed with a fungicide, and amoxicillin. I have continued this treatment for 3.5 days now and he has remained very happy and active with a ferocious appetite. The rot seems to be gone, and new growth has started - but I would love some confirmation / diagnosis from the experts.
His current colloration / Fin Condition Contrast was bumped way up to hilight any anomalies (he looks terrible I know, I'm so sorry):
And a closeup of the fin:
His coloration changed dramatically just over the two days I was away... I have looked very closely and it does not appear to be rot / growth... just looks like pigment.
Video of current behavior
The guilt of this whole ordeal had me order a 8 gal filtered tank last night. I'm hoping to give him a great home now that he seems to be on the road to recovery.
I would appreciate any and all advice as to what to do in the meantime. I will continue the antibiotic / antifungal regiment for two more days, and will frequently change water (except weekends) until the tank has arrived / been cycled / tested.
Thanks, and all the best,
TLDR? A friend pointed out rot on my betta, my treatment almost ended up killing him. He has apparently come back from the dead with a new technicolor raincoat.
