18 x 20L breeder tanks

Hi, i am looking for a free "emergency" tank please? Something not too big i can use for one fish. I would need to be able to attach a heater and filter to it if needed. Would need to come with a lid due to the type of fish I have. I am in Hertfordshire and happy to collect. Thank you in advance

I’m looking into starting a Koi fish farm , I know nothing about Koi fish but I wanted input from others on how to start small and on the right track. What kind of Koi to buy and what kind of indoor aquarium to start with first before moving towards a larger tank outside when Koi get larger

Does anyone have a marine set up suitable for a periwinkle snail my daughter thought was simply a pretty seashell And is able to collect from Hemel? I've checked and they don't asexually reproduce Just want to give this guy the best chance at survival but my fish tanks are freshwater
