So yeah, its only his head that has the pineconing look to it. I couldnt really get a decent pic of him from above, he doesnt really like the camera lol.

His name is Gideon & I havent even had him for a week, rescued him from the pet store because of his tail biting.

Could it be early Dropsy or something totally different? This is probably the best pic I could get;

Hi, dropsey usually first presents as a swollen belly thus the pinecone effect. Perhaps stop feeding the freeze dried bloodworms for now, and keep a close eye on him. You are being very proactive by getting him into a hospital tank.

He only gets one bloodworm a day. He doesnt appear to be bloated though.

[paloverde]

Sometimes as bettas age they start looking a bit coarser. ( don't we all ) He could also be scuffing up his head somehow. Good thing your on top of things. Continue to feed the same as always, and hope he gets over the tail biting.

I have Aq Salt & Epsom salt as well, should I possibly add any of those to the water?

He looks fine to me. I'd put him back in his regular tank with some clean water and just keep an eye on him. Also bloodworms, especially freeze dried, should be given as an occasional treat and not fed each day.
