Sol is my new betta and he looked great when I got him 4 days ago, but now I see he has cotton wool on the underpart of his body by his two long fins, its nowhere else on his body, just there, he didnt have it yesterday!!!
I have him in a small container because my tank got chipped, i did 100% water changes since I got him, added aquarium salt and melafix to make sure he didnt bring any fungus or bacteria from the petstore, but it seems that did nothing.... now he has cotton like stuff and I dont want him to die, I already lost 2 bettas last week, one from cotton wool, and the other for unknown reason, and Im trying to get my Precioso better from his fin rot, and now I need to make sure Sol stays alive please!!!!
His behavior went from playful to sleeping most of the time, but he still eats pretty well. the temp in his water is around 75-78 deg. please help!!
