Help! Urgent! Betta Fish Catastrophe!

Uuumm... I left home yesterday morning with my fish tank looking perfectly fine. Came home tonight with a molted shrimp, a dead betta, and another betta VERY bloated and swimming like a serpent. She looks like she's about to pop and isint using her fins at all. She's got her mouth wide open too. I don't want this betta to die too!

I had a betta in the same tank (it's a betta sorority) pass away maybe a month ago, and I thought it was from the stress of moving 3 hours away. There haven't been any other problems till now.

Tank perameters from 2 days ago BEFORE my weekly water change: 0 ammonia, 0 nitrite, and nitrate was between 0 and 5

I'll test it now and update post soon. I'm also doing a water change tonight, to be safe, and of course removing the dead betta and shrimp molt.
**Update** water parameters are in post #8

Tank mates:
- 2 betta (used to be 4, but one died a month ago, and now this one died)
- 6 pygmy corydoras
- 2 bamboo shrimp
- 1 baby bn pleco
- 1 assassin snail
- ?? Bladder snails

How can I help the fish I have left? What should I do for the bloated one? I have Epsom salt, aquarium salt, and peas. What can I do to help keep the others from all passing away too???

Thanks in advance!

**Update** the bloated betta isint swiming like a snake anymore
Here are pictures!

Can you add a picture? Remove and quaratine the sick fish. For your bettas clean water is going to help the most out of everything. What did you other betta die from?

You can try the peas for consipation but she may not eat them. Really need a picture.

Pictures added.

By sick fish, do you mean the bloated one?

The betta that died a month ago I thought from the stress of moving. I moved 3 hours away and took them with me. I thought she broke her jaw some how cause it was twisted and then turned white and a few days later she was dead. The one that just died didn't have any signs of sickness.

Honestly, I think my pleco attacked her. He's been getting kinda feisty with the shrimp. And now (pictures) he's munching on her dead body!

 

Omg your pleco is eating the bloated betta? I'm so sorry.

I had a puffer fish that was attacked by a pleco before I bought him. He had healed over so I thought he was ok just a scar. But he had sucked too much of his coating off and he died a few days after I got him. Puffers don't have scales just a coating so their delicate.

My best advice...get rid of the pleco. They get very big and more and more aggressive.

I'm so sorry for your losses.

The pleco is munching on the betta that I found already dead tonight. The bloated betta is still alive.

I'm sorry about your puffer. I've heard they're quite delicate.

I'm looking to get a better setup for my pleco to go into so he can have more space.

 

Ok glad he's not munching on the bloated one.

I would remove the bloated one. Keep his water clean. Fast him until you see evidence of going to the bathroom. Then give him a crushed pea about the size of his eye. Feed him 6 out of 7 days a week to avoid this in the future. It could also be the move. He may need some alone time to recover.

Okay, thank you

I'll have to do all that tomorrow

 

So I just checked my tank water after doing a water change. My pH is 6.4 which is pretty low compared to normal. Then I have 1 ammonia, 0 nitrite, and between 5 and 10 nitrates.

Why is my pH so low? How can I raise it?
Why do I have ammonia and no nitrites, but I still have nitrates? Is it because the dead fish caused an ammonia spike and the bb hasn't processed it yet?

 

The dead fish can. But also you moved so your tap water could be different. You can buy..pretty cheap ph tabs from like Wal-Mart and they work fast. It's the ammonia you need to be most concerned with. Do a water change. Make sure all of the dead fish is out.

 

Don't know why your ph is so low, adding crushed coral to the tank can raise it. I wouldn't do any pH additives from the store because they do it too fast and can cause pH swings which isn't safe. Crushed corals gradually raise it. The dead fish can cause an ammonia spike. None of the pictures are loading for me.

I tested my tap water when I had first moved in. It was 0 for everything, I don't remember what the pH read tho.

Repolie
I have a cuddle bone in the tank already, which helps raise the pH. It's been in there for ~6 months. Should I replace it maybe?

 

I would replace it or just pickup some tablets

 

:/ didn't get an alert for this. I did see you mention me but I was busy and couldn't find the thread when I had time. Add a new cuttlebone.

 

Awesome, will do!

My koi betta that's bloated got some peas the other night but she's still bloated (it's been 3 days). She doesn't look like she's going to pop anymore, but still bloated.

 

Look around your tank and try to see if you spot any worms— do the same with your fish and see if they’ve got any thin line looking things coming out of their vent.

I recently had a camallanus issue that started with a mysteriously puffy betta that died, turned out to be the worms. Good news is I was able to treat it.

If you notice the fish not pooping that could be a sign, especially if they’re bloated.

Will do... Again lol

I always look for worms and other things whenever I watch my fish tank. Haven't noticed anything. Thanks for the tip, I'll update soon.
