Please don't judge me, I'm a new betta owner and this was a total and complete accident. I feel awful.
I was cleaning Dumbledore's tank. Everything was going fine, I had him in a little Tupperware container for the time being and it was time to put him back in his tank. I went to take his container, and I pulled the top off (it was on loose to begin with, I had it on there so he could still get oxygen put not jump out) and as soon as I did that...He jumped out, luckily landed on the table. I went to gently put him back into the container, and he jumped again (at this point I'm freaking out) and he fell off the dresser...into a dusty old box of my boyfriend high-school football memorabilia. He was in the box for probably 15 seconds tops before I got him out and back into his tank. He immediately sank to the bottom, clamped his fins and hid behind the filter. I dropped some food on the top of his tank and he eventually came out and ate. He seems to be fine now, swimming around, digging in the gravel, resurfacing and doesn't seem to be clamping as much. Is there anything I can do for him now? His water is about 78-80 degrees so I know he isn't cold. I just feel awful.
I also have another question, completely unrelated to this. Before I cleaned his tank (just did a 50% change) there were white foamy kind of bubbles sticking to his filter, and the sides of the tank. What is that? Should I be worried? Thanks.
