Compatible fish for the higher temp water

Hi,
I’m new to the discus world.
I’ve successfully kept tropical fish for many years. I have just stopped owning a horse so I need a new hobby,my husband is hoping this will be cheaper!
I’ve got a 200 litre tank at the moment,I know I’m going to need a much bigger tank.
My current fish are 4 dwarf gourami (2 red,2 blue), 6 Betta imbellis, 4 peacock goby, 6 Sterbai Cory, 6 galaxy rasbora, 6 dwarf emerald rasbora,1 bristlenosed catfish, 2 nerite snails (and a partridge in a pear tree,)
The temperature of the tank is 27-28 Celsius ,will these fish adapt to the higher temp?
Thanks in advance

Welcome .
Your husband will be mad before you are through !
You will need a bigger tank .
The Sterbai and betta are the only fish that may handle the heat needed for disc .
I keep German rams and clown loaches with my disc .
I am the ram guy and they need the heat also ..
Rummy nose ,Cardinal tetras ,Sterbai cories ,German rams ,and clown loaches are the most commonly and properly kept fish with disc as I understand .
Many and I mean many never have any other fish with their disc …
I would not add disc to your tank as it exist now ..
Again Welcome .

Thank you for your reply.
Husband is already starting to sweat!
Thanks for the advice about the Betta and corys.
