Hey guys, I'm new here so please cut me some slack if this is impossible. I've been checking on the internet and can't find the answers I need.
My partner was keeping two goldfish in a small tank (unheated), then her brother gave her two more when he moved and could no longer look after them (not fancy goldfish but only 1 is gold, the other 3 are black, and two have many colours on them including reds and blues). The tank is way too small so I've moved them into the biggest container I have for now which is only 20L (I know, still small!). I pick up a 350L aquarium second hand next weekend and finally they'll have a nice home. My plan is to build a pond in the Spring of 2021 (long complicated reason to do with having a shared ownership property which I can purchase the remaining 25% at the end of 2020, but it's too cold to do it then). From what I've read, our 4 goldfish will grow quite a lot in the new tank in 18 months, so my plan is to acclimatize them into the pond once it's built then change the indoor aquarium to a tropical tank.
After spending so much money on the tank and an Eheim 4+600 filter, she wants more fish in our aquarium. I understand the 4 fish we have at current will probably grow quickly, but from what I've seen, there is room for more. As previously mentioned, after I've built the pond, my intention is to put all the cold water fish in there and start heating the tank inside. So are there any fish that I could buy around October-November time that would live in the unheated water inside happily, then go into the pond all year round, other than more goldfish? I've read the goldfish produce a lot of waste and even though I will be doing regular water changes, I would like a bit of variation if possible. The other alternative is any fish that can live in the unheated tank happily and healthily that could also flourish in the heated tank. The tank will currently be kept in a room and the heating is kept at 23C in this room, so I'm assuming the water temperature will be room temperature too?
I guess my ideal situation would be to buy a couple of small koi's and put them into the tank for 18 months then transfer them with the goldfish to the pond. Should I eventually not build the pond or the fish get too big for the tank before I get round to doing the pond, I have two family relatives with ponds and they would happily take them.
I appreciate you all for reading through this but any advice would be greatly appreciated.
