The betta fish is quickly becoming one of the most popular species of fish for many pet fish owners. While the betta fish was once a well-kept secret among professional aquarium fish care specialists, it can now be found available for purchase in most pet care supply stores. However, betta fish do require some specialized care procedures, especially in relation to certain health problems that are common in betta fish. Here are some of the most frequently diagnosed health problems that can affect betta fish.
STRESS
Betta fish are particularly susceptible to being negatively affected by environmental stress. Stress is a common problem among many different kinds of pet fish, and can manifest as some noticeable symptoms. Common symptoms of stress in betta fish include lethargy, clamped fins, spotted skin discoloration, open red or white sores, and difficulty breathing. Betta fish under extreme stress may also lay at the bottom of their tank, seeming to be motionless for long periods of time.
Stress in betta fish is usually caused by a problem in their environment, which may be identified through careful observation. Some betta fish may become stressed if they are currently living in poor water quality, or if they are suffering from ammonia poisoning. Betta fish may also become stressed if they have recently experienced a change in tanks, environment change (such as addition of new decorative tank elements), introduction of other fish to their tank, change in diet or undergone a stressful experience (such as a transfer to a temporary container for tank cleaning). Stress in betta fish may also become apparent if they are suffering from a health condition, such as fin or tail rot.
The best treatment for stress-related issues in betta fish is to first identify what is causing the stress, and then treat the specific problem. For example, if your betta fish is stressed due to an improper pH level in the tank’s water, adjusting the pH to the proper level will help to treat any symptoms of stress that the betta fish is experiencing.
FIN AND TAIL ROT
Betta fish are highly valued for their appearance, due to their brilliant colors and flowing fins. However, since the fins of a betta fish are larger than those of most fish, betta fish are also more prone to developing bacterial infections on their fins or tail. This is also known as “fin rot”, and is especially common in betta fish that live in poor water quality environments. Fin or tail rot may also occur in beta fish that are living in an overcrowded environment, or are subjected to the aggressive behavior of other fish in their tank.
OVERCROWDING
Betta fish are naturally aggressive fish, and it may take some care to ensure that they are not subjected to overcrowding. In general, betta fish do not thrive when kept with other fish, especially if all of the fish in question are male. Betta fish can be kept with certain species of fish, such as platies, corydoras catfish and loaches.

Hoping someone can help. I’ve had my Beta fish for only a couple of months and everything was going ok until recently when I noticed a white spot on his left side near his gills. This white spot got bigger and bigger and now looks fluffy like a form of bacteria. I cant pull it off and I’m afraid that if I pull him out of the water I still won’t be able to get it off without hurting or killing him. Can anyone suggest anything which may help before this thing kills him?
Thanks!
I have had a Betta fish for 3 years now. We had just moved him to a one gallon tank, he was previously in a small bowl. I knew something was wrong when he lost color and he lost his top fin. But I don’t think fin rot caused this. Anyway, I put in two decorations and a heater and he is just sitting by the corner of his tank. Sometimes he moves to the other side, but he never is active of doesn’t swim to the bottom. It is hard to say but can anyone tell me if it is almost his time to go or is he just being hard to get. Please help any comment will be put under consideration.
Hello all! Ok now to the serious part, i have had my Betta fish for 3 years now. He has lost his color and his top fin. And no before you ask he does not have fin rot. Anyway today we decided to put him in a 1 gallon tank and ever since he is just been sitting by the heater and doing nothing. I am worried it is his time to go soon, but I can’t be sure. Another thing is I don’t know if it is my eyes or not, but it seems to have air bubbles all over his body. If you need to know, he has just been introduced to this tank for now 3 hours, he has never had been in a heated and large living space thanks to my mom. also the last thing is that we have given him plants but he will not go near them. My mom got a fish today also and he loves those plants. Can anyone help me!?
I’ve had my betta fish for a few months now and since I brought him home he’s gradually started eating more and more. Now he eats twice as much as he did when I got him and I only feed him what he will eat in 2-3 minutes. Anyway, he’s developed a huge, pregnant looking belly. Is that healthy or should I put my betta on a diet??
Ive had my fish for about 3 years and now he has a silver underbelly near his gills and is having trouble swimming to the top of the small tank. He was in a big one my I downgraded when I noticed he was havin troubles going to the top to feed and breathe. Should I bring the water level down to make it easier?
Hey, I was wondering- I keep my betta in a glass bowl, probably about 1.5-2 gallons in size. However, my house doesn’t have consistent heating and his water sometimes gets cold. I was told not to put a heater on a bowl, but would it be advisable to shine a light on his tank so he gets heat or wrap the bowl in a scarf or something? I don’t want him to get sick because the water is cold!
If you don’t want your Betta to become stressed out and not eat, then get a different tank. Also when you get it, make sure to get a heater and colorful decorations. Bettas can die from boredom you know. Make sure the tank is not glass but acrylic. Within a couple days, if your betta is not active, it will be back normal.
I have had my betta for 3 years now and my mother decided to buy a gold fish and put him next to my bettas tank. Now my betta is grayish looking and he looks terrible. I thought this problem was due to old age. We just relocated the goldfish. I guess we have to wait and see what happens next.
i have a betta that is a light purple blue. he started out white when i first got him. his colors changes go in order : white, blue, purple, red, purple. i’ve just now noticed that he has started turning silver/white when i turn his light out at night. is this normal? his color looks like it fades and his light is only off at night. any ideas?
Betta fish get aggressive since they’re fighting fish so that’s why they seem nuts they’re just pissed so you’re seeing aggressive fighting symptoms. Stress and anger are mental problems, usually.
Mackenzie: Please see: Common Eye Problems in Pet Fish here in the side column on this site…
Food left in the tank will rot and have bacteria in a fish tank but you use a siphon system every week to clean it, you should be fine!
Hey: For all those asking about what’s wrong with their betta swimming upside down, sideways, rolling, or floating at top or bottom but not normal like floating: This could be swimbladder.
Here’s a link I found on Bettas with it. I had a goldfish die from it. He first got it, I treated it, and two days later got it again for some reason and died. http://velvetdragon.com/bettas/sbd.html
I wish you all better luck than I.
My sister got this red betta and has been here about 2 days and he just sits there and only moves when i move his bowl or put a mirror in front of his bowl. Ive done some research and he has stress it says, but i dont think so, i think hes mental, help!!!!
note: bettas are not very active fish. if u want him to do more put him in a bigger bowl or get him and exercise mirror. my proof that i know what im talking about = im a breeder.
I have had my betta for about a month, and I clean his bowl atleast 1 time a week, if not more, and he hasnt been eating for the past couple of days, and this morning when i went to feed him one of his eyes was all puffy, and i dont know what i wrong with him!
Can somebody offer advice for my betta fish. I got him on Thursday evening, prepared his 2.5 gallon tank, and let the treated water sit overnight. I got him the best of everything I could find (a nice heater that turns itself on and off, a small gentle filter on the tank that doesn’t make ripples, but cleans the water a bit, a little betta log and leaf, some plants). Then, I put him in on Friday morning. He was so happy — swimming all around, bright blue, looking calm and exploring his new tank. Then, Friday night, I noticed he was curled in a little ball between two plants and not moving much. When I woke up on Saturday, he was staring at his reflection on the empty side of the tank and thought it was another fish. He looked very stressed and was breathing fast, his color was not as bluish (tinges of red) and he looked visibly nervous. I think he thought it was another fish — he kept approaching and then backing up from the side and hit his nose several times. So, I went to the petstore and they suggested I get a few plastic plants to put on that side so he wouldn’t see his reflection. I did that and he moved away from that side of the tank and is now toward the front (which is less reflective) and just hanging there. He seems calmer. But, he has spit out all of the pellets I gave him and they are on the bottom of his tank. Could this make the water quality bad? Advice, suggestions….?
Have you tried feeding it flakes rather than pellets? Some fish if they are used to flakes (or pellets) don’t recognize the other kind as food or do not like them and wont eat them.
My fish is about 1-2 years old. Her name is flash and She just lays at the bottom against the corner and starts to roll onto his back. She won’t eat, and she doesn’t seem to move other then rolling onto her back. She also seems to be fat at the head then she just goes to super skinny at her tail, she’s floating but her tail isn’t. I love my fish and i don’t want her to die. Does anyone know whats going on? Please help, I’ve only had her for a year.
I’m having the same issue mine is a red beta too and he was doing really good then about 2 weeks ago he just stopped eating and acts really weird. He will float at the top or bottom and won’t move and when he does move it’s real fast and he repeatedly slams his face into the corner of the glass and won’t stop for a while. It’s like he has a mental problem all the sudden……is that possible? And what caused this behavior? I haven’t changed anything since I have had him. And with him not eating idk how he’s still alive.
try putting them in a bigger tank. with more places for them to hide. mine have had the same problems but i just did a complete water change and cleaned everything in the tank. if that didnt work i moved them into a bigger tank where they could swim more.
i bought my beta fish about 3 months ago. He is happy and loves his pickle jar tank, but he is black. When i bought him he was white and now he is turning black. There are tiny black lines in every scale, and it is freaking me out. My sister claims it is poop in his tank, but it is always clean! Comment if you know what is going on with my fish!:)
Bettas tend to lose their colors in the store bc they do not get fed well or have enough light. Bettas will typically change colors so there is nothing to worry about.
I am having the same problem with my fish and ive had him for a year as well. but mine lays on his side and wont move unless I moved his tank, he goes crazy around the tank as well and I’m trying to find something that will help. I’ve got another betta next to him and he was fine but now hes starting to act the same way.
I have a Beta that I have had for 1 year (RED). The last month he is laying upside down and goes crazy in the tank like he had a stroke. I have him in a 1 gallon aquariun with a filter and change his water about once a month. I have another Beta in a tank next to him and he is fine. Can you tell me whats wrong as I would really hate to loose him Thanks
oooor, you can just get tilapia which does pretty well in the cold. Tilapia is used a lot for these system because they’re good eating and they are adaptable. I think one of the tilapia species dies at 45 F (7 C)
