need urgent help! Gillbert seems to have either early stages of fin rot or a fungal infection, but I dont know which! His tail has seemed to have been fused or clamed at the black spot on the end of it, and has done the same to the top of his tail, and has even got to his back fin! I have cleaned his tank before he went in, and cleaned all the decorations, substrate and even his filter. So none of those items could have possibly caused this, right? And his tank is warm, around 75-80°. Ive noticed the black spot on his tail when I first got him, but I thought it was part of his coloration. :(
