Fish Dieing randomly!!!!!!! Help me please!!!!?

One by one my fish are dieing. Tank stocked as follows initially and currently:

6 buenos aires tetras- 4 now

2 honey Gouramis- still 2

1 peppered cory catfish- still 1

1 albino cory catfish- still 1

1 green cory catfish- still 1

1 Raphael or striped catfish - 0

I used to have a 40 gallon submersible , but recently acquired a brand new 75 gallon. I have a 150 or a 200 watt heater so the tank is about 74 degrees.

One fish will be singled out , by his own doing, then after a day or so of sadly half swimming and eating the fish will die after loosing color and kind of graying. The fish will eat and swim but by himself then swim sideways a bit. I want to know if it's a parasite problem or some disease. PLEASE HELP!!! I want to know if or how I can fix it. Salt bath or a store treatment?

    I would get your water tested, you may have too much ammonia or nitrites, maybe even nitrates. Also, I would try and raise the water temp to at least 76-78 degrees. 74 is a bit cool for tropical fish. Good luck!

    I assume this means you got a new filter.

    "I used to have a 40 gallon submersible , but recently acquired a brand new 75 gallon. "

    If you didn't continue to use your dirty filter then your tank is cycling and the water quality has gone poisonous temporarily. Do partial water changes every few days until the tank stabilizes

    My Gouramis are doing fine though? And my tetras don't want to eat and the cories are ok now.
