What's going on?!

[Little Leaf]

I have no idea what is happening to King Dedede. he swims as if he is crazy or something, and when he slows down and swims, his tail seems to stick up and drag him up (guessing something's wrong with the swim bladder?) to the top of the tank. later, he swims in a infinity sign (its a 8 on it's side) and goes to swim UPSIDE DOWN sometimes when he reaches the bottom part of his swim. I'm kind of worried because this happened when my dad put King Dedede from the 1g to the 5g and it might've been temperature shock. I'll fill out the form, too.

Have you tested your water? If so, what are the following parameters?

Ammonia: N/A

Alkalinity: N/A

Symptoms and Treatment
How has your betta fish's appearance changed? it hasn't changed at all

You have 10 fish in a 5g tank? I hope you are doing water changes very frequently like 3-4 a week. That is too many fish for a tank that size IMO. You don't mention what the tank mates are but I would bet your Betta is stressed out from being in such a small space with tank mates. I would either move the tank mates out or put him into a tank alone. I would get the water tested with a liquid test kit if that's not possible I'd do at least a 50% water change.

I hope the tank mates are not those goldfish your family bought for the holiday you celebrate....
His listing and abnormal behavior is because the water is poisoned with ammonia.

I know it's too many fish. my dad forces me to take care of my fish and I'm gonna be forced to take care of a bird soon. also, I forgot to mention that i have a mystery snail.

Unless you can lessen the stock in the tank there's nothing I can suggest to help your Betta. You'll be able to keep them somewhat healthy with very frequent water changes but they'll just be surviving not really thriving. Somebody else may be able to offer you something. Its just too much for a 5g.

great now i feel like the worst fishkeeper that ever existed.

I know this will sound cruel, but because of your problem with your parents over and over and OVER... Euthanize your other fish. Tell them the fish died because THEY killed them because the tank is too small. And tell them you don't want more fish. More fish come in, euthanize. I am suggesting this because it is a lot more humane that making everyone suffer including your betta. I am surprised he has lasted this long to be honest... You aren't the worst fish keeper, but your parents are getting closer to the worst role models on earth.

Clove oil: mom and dad might have some in the bathroom, if they ever have tooth aches. Use it.

I really don't want to mention the next one, since you're just young... But smashing with any blunt object, is another method. Gruesome, and I can't do it... But a way to do it, is place them in a bag with minimal water, put the bag into another bag, make sure there's no air in there, wrap with paper towel, smash, and throw away. Don't look at it.

Or find someone who wants fish to feed their bigger fish. It's also seen as cruel, but if I had a choice between swimming a mile in bleach (ammonia) or being eaten by a shark... I'd head for the shark x.x

That's the best way. Make sure to do it without any pain and since your parents are not so good fish keepers then it's all you can do.
