What are the water parameters of the tank
Ammoniaa
NitrIte and
NitrAte
pH
KH/
GH
TDS
if you know any of those.
Also if you have an air stone I would add it because of the increase in temperature reduces available Oxygen for the fish. Or you can reduce the water level a couple inches so the water splashes back in, aerating more.
