I think for me, the Zen feeling lasts for about the first couple of tanks. Then invariably, something happens like my siphon falling onto the floor, me tripping over a cat while carrying a full bucket of water, me forgetting to unplug the heater, me spilling water on the electrical socket, the filter in the goldfish tank falling at such an angle it sprays 40 litres of water over the rumpus floor
My fish have this obsession with waiting right under where I'm re-pouring the water into their tank. Then when they get blown around everywhere, they look at me like
I did it.
Luckily all my tanks are going to be in my room from today so no more trudging up and down stairs. Now I just need to convince my dad to knock out the wall between my bedroom and the spare one, and install a sink...
