I'd like to upgrade my betta tank and a 12g long seems perfect. Great dimensions (35.4L x 8.3W x 9.4H), with lots of swimming space without being too tall. The shrimp would love it too. However I can't find any for sale. I think Mr Aqua made them but they've been discontinued. Anyone know where I can buy them in the UK? Ideally not too expensive. One with a lid would be preferable but I can make a DIY one if not.
