Ok time to ask for advice. My delta tail "The Big Guppy" is rapidly losing his fins.
I think he tore them on a decoration a month ago. He was swimming up a tiny hole in a plastic decoration and as soon as I figured it out I removed it. He is not showing signs of illness. He eats new life spectrum 4 or 5 pellets a day, they are small .5mm size. Once a week he gets 3-4 frozen (thawed) bloodworms. I just picked up some frozen brine shrimp and will be adding that once a week. I also give him and all my fish a fasting day.
I have been doing water changes every other day about 30-50%. A few weeks ago I removed everything from his tank and did 100% water change. His bio-filter is solid I test daily never saw a spike in ammonia or nitrite. Readings are:
Nitrate about 10ppm or less with frequent water changes.
I read about aquarium salt baths so one day I put him in a 2 gallon QT and slowly added dissolved salt over a few hours. He hated it and sat for a while with clamped fins. After 12 hours I slowly acclimated him out of the salt bath and put him back in his tank as it seemed to stress him.
There is so much information out there about treatment and finding the root cause. Methylene blue, antibiotics , salt etc.. I do not see white spots or blood streaks, but some black edges. Does anyone have experience with this? I would be grateful for any advice.
Oh, he is and has always been alone in a 10 gallon filtered tank with baffled outflow.
