Bichir swimming tail-up

[BlacksmithFishkeeper]

My 6 inch Senegal Bichir has been swimming with his tail end pointing almost strait up. It's not constant, he is able to swim normal. I'm just concerned because he didn't used to do this, and suddenly started doing it frequently. I've mostly observed it while he's eating bloodworms off the tank bottom. Is this just a personality quirk or is he sick? He eats well and seems otherwise healthy.

Some trapped air. If persists then try some epsom salt 3 tbsp per 5g. Should corrrect itself on its own sometimes.

One of my Dels did this a few days ago after eating a bit to much pellets (but the back not as high up as yours).
I made a non-feed day and it went away on its own.

My 4 1/2 inch sen is also doing this but not as high up and he refuses to eat
