I rescued a betta from a neighbor that left it behind when he moved. I had it in a 5 gallon planted tank with a heater and sponge filter and all was well. My water parameters were just right. Then I moved him to a 10 gallon because I read they like more space. After that move, even though the water parameters were still good he got fin rot. It progressed quickly and he now looks like the photo shown (not only fin rot but fungus on body and gills). I went by Aquarium coop's suggestion of a 1 tablespoon aquarium salt to 1 gallon water treatment for the condition. All plants were removed first. I am on day 3 of this salt treatment and he is no better. He still is eating so I have hope for him. The ammonia went up to between 0 and .25 when I removed the plants. My question is this: Should I wait and see if he improves in the salt treatment or should I switch to the trio of meds that Aquarium coop recommends for this condition (Maracyn, Ick-x, Paraguard) and remove the high salt and put my plants back in? I don't want him to decline further.
