REALLY BAD NEWS
Knock-knock, the ITTY-bitty betta I rescued from Walmart yesterday has started pineconing
I am treating him ith wMaracyn II but I honeslty do not think he's going to make it
He pooped this morning (it was brown, but REALLY thin and stringy)
I JUST got him to eat something
I tried getting him to eat a bit of crushed pellet this morning and he ignored it, I soaked a pellet in garlic, again he ignored it, I offered a frozen bloodworm and he ignored it
I finally took him out of the tank (he was floating in the sorority for warmth) and spent about 15 mins wiggling a bloodworm in front of him... he was ignoring it then snapped it (I have a picture with it in his mouth... not ure if you can see it)... he spit it out though... I tried again, and this time he kept it down...
Im totally lost on what else to do for him

He sits in the same spot, only swimming up for air then he sink right back down
I tried to get a picture of the pineconing, but sucky camera (BFs phone):
Food in his mouth (this is right before he spit it out)
Food in his mouth (you can see my other attempts before I started wiggling the BW... water is clean now and medicated)
Trying to hide from me (right after he FINALLY ate)
And you can see his poop in this picture :-/
I have labeled specific stuff for him since I don't know what is wrong with him... if he passes, the stuff will be tossed just in case...
Does anyone know what else I can do?
Any suspisions on what could be wrong????
