I don't know if I am just over-reacting or if something is wrong. I am noticing Bubbles is getting lighter in the face area. He is eating just fine. Swims around some. He usually finds himself a nice little lounging area within my plants and just hangs out.
I guess what I am stressed about now is his coloring. Here are 2 pictures showing the difference. He was darker in the face and now he's turning to a light brown. Also his "flare area" (not sure the technical name) has this rust color. It was there in the earlier picture, just not such a bright rust color. I know the lighting in the 2 pictures are different but it's the best I have.
Here the pics I took when I got him 2 weeks ago...
Anybody have any ideas on what this could be?
The temp in the tank is 76 (I bought a heater but it's faulty and doesn't work...now is going back). The PH is 7.6. The last water change was yesterday...100%. He is in a 1 gallon tank still. I pick up the larger tank on Tuesday from the post office (missed the delivery today..boo!)
