Mom's betta, in 5 gal tank with live plants and driftwood and black plant sand. All peremeters are excellant.
For last 2 mo betta has been only laying on the bottom of the tank and never comes up for food. Many times thought dead but when you come near him he'll finally swim away only to go back to spot. Not lying as normal fish would or even sick betta (going on nose) ... he is lying FLAT on his side as if dead.

Bright red and is starting to lose color. No telling how old he is. At least over a yr.

Have even tried throwing 2 guppies in just to see if he was bored. He didn't even blink at them so we put them back in original tank for them.

Usually I can figure out what i wrong but not on this one.
