from what i see , your tank should around 40-45cm length, these fish you keep put alot of stress on small dwarf shrimps,
yamato are well known jumper, you may want to check behind your tank on floor for any dry prawn.
Adding coral stone , will increas ph, gh , kh and tds , if your water is more acid , it will help buffer it up, don't put too much, one to two small
old rm0.50cents  coin size is enough.
Create more hiding space for shrimps since after molt they very vulnerable to attack.

i gone to east aquarium in ipc and seen 2 shirmp displaytank  before 3-4 week ago got many fire reds and crystal.  now got no shirmps.  i think they use ada soil and co2 and  hangon filter. 

i ask the staff. one said sleeping.  i ask another man alone and he said don't know with grin.   

Fishes produce lots of waste. Beside, ur borneo sucker may disturb the under gravel and cause ammonia tat trap under it to release. Kill ur shrimp like a toxic bomb.

I tried keeping fish and shrimp together in 45cm.
I had a tough time maintaining the water parameter.
now I just keep shrimp. Peace of mind.

no need to change water, no need to feed .... and from the bottle, seems like no air circulation at all   

got ppl selling in malaysia alreaady 

depend on what fish ,shrimp is always part of the diet of fish in the wild.
temperature 27-30c is still ok for cherry shrimp, co2 use timer to control it and not to overdose that will suffocate the livestock in tank.
