Betta Fish Health & Wellness

I got a baby betta fish and was wondering how do I care for it : as in habitat , water changes , feeding and heating

My betta fish is no longer eating and is lethargic and dull in color. He lives in a 10gal tank which is both heated (80 degrees) and filtered. He isn't interested in me or any food I try to offer him, and it's been like this for a few days, with the no eating issue going on for about a week. I have tested the water and there are no issues with it, and a water change was completed shortly before he started acting funny. I've only had him for a year or so, but I bought him as an adult.

He's a full grown betta fish, I've had him for a little over half a year, adopted him from a friend. He has a filter and a heater in his tank & I try to stick with recommended products. As of the last couple months, his fins are curling up in the back and he will only eat one pellet every other day or so. I had been feeding him three pellets twice daily. Last week I started cleaning his 1 gallon tank twice a week instead of once a week, and am considering upgrading to a 2.5 gallon tank instead.

What is wrong with my Bettas end fins?

Betta fish is spending all day at the bottom corner of his tank and barely eating. He moves quickly when he does swim and his appearance seems fine

Hello, I am writing on behalf of my male Betta fish. I believe my fish has marine velvet. Some of his symptoms are lethargy, color fading, trouble swimming, and a rust colored patch on his head. His water is also somewhat murky even after a recent water change. He is in a 1.3 gallon tank, and is the only fish residing in it. I am worried for him and wonder what to do. Please let me know your opinion on the situation, and some possible treatments.

My male Betta fish isn’t moving

My male Crowntail Betta fish is acting very lethargic, he stays at the bottom of the tank and only coming up for air, barely eats, his stomach looks hollow, and the scales along his back are raised. He has been this way for a few weeks but isn't getting better. I change his water weekly, and he lives in an environment where his is not caused stress.

My baby betta that we have had for four months is having what seems like seizures.

I just got a Betta fish from someone a week ago (she had him for about 2 months). He's in an unheated, 1 gallon tank. I didn't know it was bad to keep him in there until I noticed some white stripes around his gills and his eye over night; also some discoloration. I learned on the internet it's not good to keep them in this environment (just changed his water). I'm not sure if it's Ich, Popeye, or finrot. How can I cure him quickly so he doesn't die soon? (Get a new tank, medication, etc.?)

My betta fish is turning white!please help!!

My betta is a baby boy (4monthold) When I first got him he was red with white. 2 months ago his growing fins began becoming blue. Abt 3 weeks ago I see that he began losing his color a bit& began becoming kind of transparent, so I took the water to get checked& the water was good but the store couldnt check for ammonia cause they had ran out of that test(water has conditioner). Last night I notice that he started getting a shiny silver color on 1side of mouth& in gill. But he is acting normal
