RE the getting stuck to the intake of the filter.
He is weak so that would be why to use a piece of filter pad to soften the out flow, but another option is a plastic needlepoint canvas from a craft store to surround the filter in an arc shape to help diffuse flow and keep him away.
This is the plastic needlepoint canvas, comes in clear, green brown, btw from different stores...

Keeping him in a smaller container might be easier since you are changing the water every day. Or after feeding. Live Brine shrimp are great to get them eating more maybe get his strength back. You may have a lfs around which sells them, you can always ask too, if they know someone who raises them or if they have some they raise for their own fish, you do not need a large amount.
Frozen food defrosted is also a possibility. Blood worms or black worms are hard for them to resist.
