Hi I have a 29 gal. tank with 2 neons, 1 zebra danio, algea eater, a sick clown loach, and 5 tetras. I just done a 50% water change cause the filter was nasty and didnt know till fish started to die, and now after 4 days my loach is covered in ich. He hides pretty much all the time so I didnt catch it fast. I put Copper Safe in the water and raised the temp. from 79 to 85. What else can I do? Also is any of these fish invertibrates? I hope not cause Im suppose to remove them from the tank. Ive had this loach for 2 yrs and this is the first time its ever been sick. Please help me its our fav. fish. Also one of my neon tetras has dark places on it and its color is now dull. It is about 2yrs old also. Does this happen with age or is it sick too? Im not use to sick fish so I havent a clue on what to do. Thanks so much for trying to help me save my baby.
