Hello all. I have a 5 gallon tank, heated to 78-80 degrees and filtered. I cycled the tank for about a week and added in my Betta and four ghost shrimp after checking water levels (nitrite, nitrate, ammonia) for three days, all of which were safe.
For a couple of days he was fine. Now he's mostly been floating above the thermometer not moving around much, and I've noticed that he has a white spot next to his gill now. Itís only on his left side. He also isn't eating very much, and his fins seem collapsed. I feed him Betta pellets, and have some freeze dried bloodworms on the way in the mail to try. He'll look at them when I drop them in and even swim over to them, but then just takes a gulp of air and goes back to his spot over the thermometer.
Does this white spot look like Ich? I took a picture of him the day I got him and it was not there. Or could it be a fungal infection?
If it is Ich, I know I can just raise the temp of the water. Will the Ghost shrimp tolerate 85 degree water if I do this?
I took care to prepare everything very well, and I'm concerned I did/didn't do something that I should have. Thank you in advance.
PS: The first picture is the day I got him, about 3 days ago. The second picture is today, with the white spot.
