Juwel Rio 180 aquarium setup

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

Looking for a small tank with a lid and built in light please - want asap

Looking for a 4 to 5 ft tank for my turtle any rocks or any sort of bits I could use it to be brilliant for mine and my 3 year old son’s project in the Southampton local area to me
