Recently, like the couple weeks my fish has been staying on top of the later and can't seem to swim down to the bottom of his tank, or even try. He also just floats back up without actually swimming. From what I've learned so far, this is SBD? I don't know how to go about treating this though.
He has not eaten for the pasted three weeks. I just bought some smaller pellets in case his other food was too big and am soaking them in garlic. He swims away from his food if anything.
For the past ~2 weeks I have been treating his Fin Rot with Aquarium Salt and everyday 100% water changes, it does not seem to be getting worse. He has become very thing though and his color is starting to fade. He just won't eat anything and he floats on the surface all day. He can't even swim right.
I am using AquaSafe (By that Tetra brand) on my 2.5gal tank, it is heated to about 72-74. I currently cannot afford a better heater that is not preset. His tank is not filtered and he has one of my old ceramic mugs in there as a cave which he liked before not floating to the top (could this be making him sick?).
I was thinking about trying the API Stress Coat to see if that would help promote healing, unless advised otherwise. I use 1/2 teaspoon aquarium salt for every half gallon because of the fin rot. I wasn't sure when I should stop treating and if I should just use a regular amount or not. Is it compatible with the API Stress Coat if I were to use it? I was using Melafix but was advised against it and just used the salt.
Let me know if you need more info please.
