betta sick

I would looking into finrot if his fins are ragged and falling aparts

I would try doing daily water changes to keep his water as pristine as possible. This method is often very effective with fin rot which is what it sounds like he has.

How is he doing?

Hello,

I have a crowntail betta as well. Ive had him for almost a month now. Hes usually very active and a bit of an eater. I have been away for a few days (my brother fed him while i was away). i noticed he stayed at the bottom of the tank a lot today which isnt his norm. Hes normally a happy little guy and likes to nap on his leaf. His fins are normally spread out as he swims but he has had them a bit clamped today and was not eating as much. He also started darting around which concerned me. So i changed the water in his tank to see if that would change things, it hasnt and im worried. I used my flashlight to get a better look at him and noticed a little bit of gold shine to him. He has a natural iridecence to him but im not sure if this gold has always been there. I have him in a 3.5 gallon tank with an air pump filter (that i turned off just now to see if that would help).

Please help, im worried something is wrong. He had made such a lovely bubble nest before last weeks water change and now he isnt acting himself.

Here is a photo I took tonight. I took some video as well but Im not sure how to upload it on here.
