poor fish, yes it looks good, but imagine only having just enough room to barely turn around, it would be like living in a cupboard. there is barely any surface area for all that water, and i imagine gravel vac the bottom is near impossible too so all that waste just sits there. these types of tanks should be banned. shops see pound signs, same as the companies that make the tanks, put a picture of a fish on the box and everyones happy, apart from the fish. its as bad as those tiny 5 gallon plastic tanks in shops listed as 'goldfish' starter tanks, goldfish need huge tanks, even fantails which stay smaller need 10 gallons each. i cant abide tiny tanks, every fish should be fully researched and their adult size taken into consideration before even buying a tank. i hope you keep up with the maintainence on this little tank, weekly gravel vac and partial water changes with dechlorinator in your tap water. try not to miss out on them for the fishes well being
