23C is really cool OoO
73F !!! u just have to wait for that heater?
ask your mom to go petsmart or petco or any LFS
now to get a cheap heater.
tell her if she doesn't get it now u gonna lose your love clownfishes which porbably more expensive than a heater...
in the meanwhile feed a little more to your fish, so they have more energy, just a little bit.
and pray for them, hope them they can stay one more night, temp get much lower at 4am~6am.
if u can't get the heater tonight, maybe keep the light on for just tonight?
Thanks to AMD, HN1, Zero, partypalooza, thincat, and thominil who helped me in almost every questions. Thanks everyone!!!!!
