Yay, i am glad they are looking better
There are things you can do in power cuts to help your fish, If you have a heater you can just put a few blankets over the aquarium to keep it warm, But i imagine it is pretty warm in south africa
Also if the power is out too long like over an hour you can stir the water every 20 minutes with your finger (for 5 minutes)to create surface movement and oxygen to keep them happy until the power comes back.
It was winter in England and i had a power cut for 8 hours i panicked and wrapped the aquarium in foil (that you use to wrap food with) with blanket on top
to keep the heat in, it worked and raised the temperature by 1 degree
I turned the filter off and placed it in a bucket of their water.
I stirred it every 30 minutes and they were fine afterwards.
There are things you can do that don't require money. But the filter would be the biggest problem with long power cuts, they always say to turn off the filter if a long power cut is expected,if the filter sits there full of fish waste with no power it can filter bad bacteria back in to the aquarium when the power comes back on again and can cause water problems and fish illness,
i did not explain that very well
I am sure there is someone on here who can explain that better than me. But what i did above did work for me.
I hope that helps a little for your power cut dilemmas.
