When fed he swims around the tank as he always has but
when the food's gone he just sits on the bottom. He wasn't doing that
yesterday



Everyone is giving you really good advice...
I know you're concerned about the fish- you probably check on them fairly
often.
If when checking you offer food to test for responses you could be
overfeeding and adding to any problem. Try to resist the urge to feed too
much- sometimes nursing means witholding food as well.
Just a caution...
