I noticed that my fish was swimming around with a weird looking poo... it wasn't stringy like normal fish poo is. It looked like a little ball (I took a picture).
Is this bad?
Also, he hasn't been eating like normal (granted I don't really know what his "normal" is, since I've only had him for 2 weeks) but he used to gobble his food down! Now he is only eating 1 pellet per day and 2 if I am lucky. Could he be constipated?
Another thing, his fins (he is a crown tail) look odd to me. It seems to me that they looked fuller when I first got him, now they look like they're thinning? I don't think its fin rot since it doesn't look like it is getting shorter, just thinning... could he be a biter? Or does fin rot also make his fins look like they're thinning? They just look stringy.
I don't have a water testing kit yet. Will be getting that when I go home for Christmas break. Also haven't ordered a heater for him yet, since I won't be here during the time that they would ship it (I'm hoping to get one from pet store in my hometown).

Symptoms and Treatment
How has your betta fish's appearance changed? nothing other than his fins.
How has your betta fish's behavior changed? spits food out. quit working on his bubble nest
(i think that is because the weather started to get colder. his water used to be very warm on its own, that is why i did not get him a heater to begin with).
When did you start noticing the symptoms? has been spitting food out for a week now.
Have you started treating your fish? If so, how? not yet.
Does your fish have any history of being ill? not that I know of.
How old is your fish (approximately)? No idea. I just got him about 2 weeks ago.
I would like someone to help answer/give advice on all 3 concerns: strange poo, spitting food, and odd fins.
