If maracyn has not worked try maracyn 2  one treats gram positive and one treats gram negative bacterial infection  its bacterial or viral infection looking at pictures add aquarium salt one table spoon for 2gallons with maracyn 2 salt will damage you plants at that level

[New Cory disease]

[Betta help]

I would increase the number of rummynose tetra to 20 it will give a better effect I think you stock plan will be fine as long as you have good filter and regular water changes

[Hatchetfish with long strings]

Looking at symptoms you fish is displaying I would treat for internal parasites

[Flat worms]

I put shimp wafer in my tank to day they were hundreds of worms on it

[Pea Puffer not doing well with weird white spots under mouth]

It difficult because it  could be fungal or bacterial infection looking at the white patchs with meds you have used has there been any improvement and how much salt per gallon did you use
