Hello! I'm hoping maybe someone can help me solve this dilemma...
My betta Gulliver lives in a 2 gal filtered heated tank, I do 50% water changes every week. About a month ago I started adding aquarium salt to the tank (1/2 tsp per gal) and having run out of food, started using something different. By accident I got flake food instead of the pellet food I had been feeding him. It took him a couple days to get used to the flakes but now he seems to love them!
Just recently I had to move the tank to a different room in the house, (maybe 2-3 days ago. Since then his color has gone from a beautiful dark blue to a splochy grey color. I've done a lot of reading about losing color and think it could be one of three things,
1) he is stressed from the move. Though he has been through tougher moves than this one so it seems unlikely.
2) he has some sort of bacterial infection. Besides the color change he is acting perfectly normal.
3) he's becoming an old man and losing color because of age, but I've only had him a little under a year...
Attached (I think) are before and after photos..
Which is most likely? Am I missing something? Should I be really worried or will time fix this? Is there something I can do?
