thanks for the tips. 
 
i cant figure it out. didnt have this problem before. my water is fine 7.8 ph, 0 ammonia, 0 nitrite , 5 nitrate. temp is at 71-78. wc weekly about 15%. tank has a painted back and not in direct sunlight. tank is not overstocked. all food are eaten after feeding.
 
i will scrub it this weekend and do a 33% wc and see how it goes. i will also take some pics. zennzzo , i think you would like my new fish!
