I have a new betta that I purchased about 3 days ago. He shares a 30Litre tank with a platy. We did have 2 platy's but 1 died yesterday, and still not sure why!!
My betta looks very depressed, never fans out his fins and just lays on the bottom or in his cave all day.
I did about an 80% water change yesterday after the platy died and pH, temp everything is fine today. (I had the guy at the pet shop test my pH) and temp is 25C. He has a cave/ornament thing to hide in and a plant. Neither have sharp/rough bits so they aren't bothering him.
Platy also seems to be a little depressed today but I know they like to have other platy's around and I haven't managed to get him a new friend yet.
My Betta was fed day before yesterday and hasn't really hung around the top looking for more pellets so he didn't eat yesterday, however I tried to give him a couple of pellets today when he came to the top for air but he just spat it back out and then swam away so didn't seem interested in eating.
Really worried he's not well but can see no change in colour/brightness, no sign of spots, shedding or anything like that.
He just looks so miserable!!
