Betta Fish: Mold is acting odd and bloated

Mold hasn’t been fed for 3 days because i was out of town (i told everyone not to feed them and they are extremely respectful of my fish, i see no signs of foul play)

Mold has his own 7 gallon tank where he is the only resident, i do weekly 25% water changes treated by sachem prime

The darkened picture is him just waking up, when i noticed he was acting strange

Parameters using api liquid test kit

Ph- 7.4
Am- .15
Nitri- 0
Nitra- 2.0

I noticed some bga in his substrate and scooped it out with the vacuum
Rinsed the sponge filters out using tank water
There has been a copepod boom lately
Vacuumed the substrate really good

Medication on hand:
Kanaplex
Methylene blue
Catappa leaves
Garlic guard
Daphnia that he refuses to eat (even with garlic juice)
Baby brine shrimp he refuses to eat
He will eat shrimplets, will they provide enough of what daphina has for him to poop if constipated?

So far he got a brief aquarium salt bath and i added a pinch of aquarium salt in after a water change. Anything helps
