Fish Tank Temp

[ApistoNut]

i have some small tanks for breeding at the moment, i have got heaters at lowest setting but as the air temp is very high at the moment my Apistogramma breeding tank topped 27.2 is this safe? there still alive for now but what can i do? if i turn off the heater then the temp will drop immensely at night

Should be fine, just leave the heaters as they are, turn the lights off if possible.
