Need ich advice

[neoh]

He may be too far gone I'm afraid - and chances are likely, it will spread. I know this is tough to swallow, but you need to get him out of there. You can drain all your water to catch 'em, or get a trap - but he needs to get out. I had something similar that wiped out all the fish. I managed to get them into quarantine and did hyposalinity treatment for 2 months until no visible spots were seen, then put them back in. The only fish that was not effected was my scooter dragonet.

One of the reasons why fish seem happy and healthy at a LFS, then come home with ich - is they are under copper treatment during the shipping process from wherever they receive the fish. Once they are out of their copper environment, the parasite manifests. Always quarantine! I unfortunately learned the hard way.
