What size is your tank? 4L
What temperature is your tank? 24°
Does your tank have a filter? no
Does your tank have an air stone or other type of aeration? no
Is your tank heated? no. I just keep my room really warm to keep the tank warm
What tank mates does your betta fish live with? none (if you want to be technical he is in an 8L barracks with Zorro my red CT but it is completely divided).
What type of food do you feed your betta fish?
Zoo Med betta floating pellets, sometimes some Nutrafin Max Betta Colour Enhancing Flakes, and very occasionally freeze dried blood or black worms
How often do you feed your betta fish?
1-3x a day up to 5 pellets total but usually between 3-4. He also gets a fast day or 2 a week.
How often do you perform a water change?
25% 2-3x a week
50-75% 1x a week
I also make sure to suck up all his waste every water change
What percentage of the water do you change when you perform a water change?
Anywhere from 15-100% but above is my usual schedule/amounts
What type of additives do you add to the water when you perform a water change?
Marine Master Water Ager. It says on the front it "Removes harmful chlorine & chloramine from tap water" - I'm going to change brands because I've been told it isn't very good and I don't like how I can't find out the ingredients
Occasionally put in 1/8 tsp AQ Salt.
Have you tested your water? If so, what are the following parameters?
Ammonia: it should be 0 last time I checked
pH: I'm pretty sure it is 7 but I lost the colour card (I'm using API liquid pH test kit and it came out green)
Symptoms and Treatment
How has your betta fish's appearance changed?
He was bloated but not severely (it looked like he had eaten too much kind of distended)
His spine went in the "S" shape.
Not lethargic but he physically couldn't be himself; I saw him try to flare but he couldn't extend his gill covers (not sure of the actual term; mind blank).
He looked like a balloon swimming.
How has your betta fish's behavior changed?
He couldn't swim away from the surface so part of him was always exposed to the air.
He also seemed peeved that he couldn't flare at Zorro or myself.
He always seemed alert and tracked me with his eyes and tried to "greet" me as best he could.
When did you start noticing the symptoms?
3 days ago although the day before exhibited symptoms was his fast day and technically he had fasted 1.5 days before he exhibited symptoms.
Have you started treating your fish? If so, how?
Yes as soon as I realised he wasn't dead (I woke up to see Albus floating so my sleepy brain jumped to conclusions) I fasted him but since I had an end of semester exam I didn't really have the time to do much else (first I made sure he wasn't suffering and that the water seemed clean).
Once I came back to my dorm it was pouring and so cold (my hands/feet were blue) so I couldn't go out and get him anything (I was thinking maybe Epsom Salt). So instead I did a 75% water change and used 1/4 level tsp of AQ Salt because I figured as long as there was some ions creating an imbalance it would help to draw some stuff out of him.
The next day he could swim downwards but couldn't stay down without help from his silk plants (much to my relief because his side was always exposed to the air) and I did another 25% water change without adding AQ Salt.
Today he seems almost normal but his spin is still "S" shaped a bit
Does your fish have any history of being ill?
How old is your fish (approximately)?
Although he seems almost normal though I feel like I have failed him.
I also feel really confused because my other male is fine and he normally gets fed 1 pellet extra than Albus.
Like some people said to put him to sleep but I read somewhere that it isn't painful so I just can't justify ending his life prematurely.
He may not be the prettiest cellophane in the world but he is my Albus and I care for him just the same as my other fish.
I'm thinking he is predisposed to this condition because he has always had the slightest kink in his back (you could only tell when he wasn't swimming and if you looked for it).
I want to know what should I do if this happens again and any other thoughts/opinions/information. Like whether I should feed him less from now on, should I treat him any differently than any of my other bettas? Stuff like that.
He has already fasted for 4 days now so I've fed him 3 pellets today because he seemed fairly normal.
p.s. sorry if this is in the wrong section but I really want him to be okay
