Her water is still 80 degrees, so I scooped out some water from her tank, mixed 1 quarter tsp of aq salt (there's about 1 litre in her tank) made sure the salt was completely dissolved, mixed it a few more times, then poured the mixture into the tank where she was. I poured it in at 1 47. Do I need to stay up till nearly 2 am so add another quarter spoon??
I changed Jewel's water, replaced it with 80 degree tap water. Conditioned it, hoping the heater will maintain the temperature. I am leaving all the gravel and plants out for now. I will start the salt treatment after lunch. I have several pictures of her in my album. Please check out the one called Does Jewel have external parasites, to see if I diagnosed her right.
Jewel is breathing better now. However, I think she may have pop eye. Her eyes are slightly raised, she's a bit lethargic, and her one gill is definitely raised away from her body. I know when they use their gills, they will go away from there body for a moment, but her one gill is always protruding away from her body. I took several pictures of it but when I upload them onto my laptop, those particular pictures aren't detected. I have uploaded many pictures in the past. I am going to check out the beta fish diseases to ee what I can find, and hopefully trest Jewel.
If it is an "all-in-one" cartridge that is filter floss with carbon inside, just rinse it once a week in tank water or dechlorinated water. Most of the filters use those kind of cartridges. If the cartridge becomes too old or starts to fall apart, put a new cartridge in the filter but keep the old one behind it for a week and monitor for ammonia spikes.
