I'm sure this has been covered in different threads before (I pretty much exhausted the search function trying to find an answer before posting) but I just couldn't find an answer that applies exactly to this situation...
Yesterday, my partner and I were given two bettas for Christmas by his family. I know, it's terrible. I'm pretty sure they weren't doing it carelessly, knowing how much we care about Falkor, but still...
Anyway. One of them is doing fine, after being put in a temporary home until we do an emergency shop today for a new tank he's become active, has coloured up a little more, so I'm confident he'll be okay.
The other, however, is not doing much except lying at the bottom of the tank. I put him in the only spare tank I had, with my spare heater, because he looked the most in need of the two for heat and comfort. The poor little guy just doesn't want to do anything except lie there. He did colour up dramatically with one night in clean, warm water, but he's not interested in food and won't budge from where he's lying unless he needs air, or doesn't like something that's placed in front of the area he's lying in. Then he'll just turn around, swim a little way, and just keep lying there.

How often do you perform a water change? I have not yet in this tank, he has only been in it for 14 or so hours, but will be the same routine as Falkor's - 50%/week + 100%/week if not heavily planted, 2x50% weekly if heavily planted

What type of additives do you add to the water when you perform a water change? Prime + IAL + ferts for plants
Have you tested your water? If so, what are the following parameters?
Symptoms and Treatment
How has your betta fish's appearance changed? He has coloured up, which is positive, not a worry.
How has your betta fish's behavior changed? It hasn't changed, but in the day we've had him he's been lying at the bottom of his vase, and then tank when we set it up. Uninterested in food, lethargic.
When did you start noticing the symptoms? Immediately after being given him.
Have you started treating your fish? If so, how? I have put him in a reasonably sized, heated tank, much better than where he was in a cold, tiny vase (ugh) and keeping his water clean.
Does your fish have any history of being ill? Unsure, we only just got him.
How old is your fish (approximately)? Again, unsure, but he looks younger than the other betta we were given.
Any help is very much appreciated. Despite not planning to grow our fishy family just yet, I really don't want to lose this little guy, the poor thing should have a chance to live happily.
