I have a small fish tank in the lounge. Strictly speaking it’s a nano tank, and while I know these are not ideal, it works well and is on the larger end of the nano tanks. I have a small number of tetras and some penguin fish in it. Like any other tank, it needs cleaning from time to time and today was a cleaning day. I scrapped off the algae growing on the side of the tank and gave the glass top a good clean too and it’s amazing how much that helped it look better. Now clean I was able to top it up water wise, adjust the pump flow and give the fish a feeding treat for having to put up with me ‘invading’ their home. A few hours later and they seem quite unfazed about it all, either that or they are stunned with the new view they have through the glass.
