Hi folks, I'm hoping a few here keep carp indoors.

I've been offered a reasonable sized tank and fancy keeping a few mirrors in it. How difficult is it to keep the water at a suitable cooler temperature. Especially in the winter when the central heating is on. I'm assuming their pretty hardy and easy enough to keep if the water temperature is ok.

Thanks for any help.

Don't do it. They will outgrow any tank in no time. Only suitable for a decent sized pond. Trust me I've been there.

Don't need to be worried about keeping them cool mate. Unless you live in a sauna the water temp will never get too hot for them.

They will outgrow the tank pretty quick though so make sure you have somewhere for them to go...legally of course. You'll need a good filtration system and avoid sandy substrates.

Trust me you will need a pond in no time. Carp in warm water with good feed will outgrow an aquarium in no time. Remember you can't just dump them in the nearest water or you risk a fish kill.

Gutted, that's that plan out the window. I'm assuming koi are the same? Sod goldfish, might have to be tropical then

Yep exactly the same. If you want some interesting fish, get some American cichlids. Not the easiest things to get hold of, but way more interesting than the more common Africans imo

Some of the ornamental goldfish species are quite nice (Fantail, Pearlscale etc.).
If you do end up getting into fishkeeping then I would recommend reading up on "the nitrogen cycle of an aquarium" before starting out.

We've kept fish before but the usual temperate ones. It kept the kids happy for a day I'll look into the suggested. So the ornamental goldfish won't keep growing?

Thanks for your help folks.

Yes they will keep growing mate. Slower but they'll outgrow a tank at some point.
Siamese fighters maybe?

Depends how big your tank is really.

I don't know the litres of it, it's a reasonable size. For fighters you'd need like 10 to know they were in there but I wouldn't be happy having any more than 5 4” goldfish. Been looking at google and goldfish ‘aquascapes', some of them look epic to be honest. Might go down that route 🤔

I took home some carp fry from a local lake 20+ years ago (with the owners permission) and kept them in a small tank in the flat we lived in at the time.

Within 2 years we had moved and moved the fish into a small outdoor pond, now, two moves later those same fish are in a pond of 10,000 gallons just outside my back door.

The biggest mirror, Jaws, as christened by my step daughter when she was 3, is now well over 20lb.

Given that they live to 50 years plus keeping carp in an indoor tank isn't ideal.

Fair point on age, I hadn't thought of it To be honest. There's a cyprinid of some type in my grandparents pond that I caught and put in when I was a kid. It's been in there around 20 years and Still going strong. Their hardy buggers thats for sure.

Thoughts have now turned to finding the most obscure goldfish we can find. Bubble eyes are on the list

I had a small common of about 4” in a tank in my late teens, the bugger kept jumping out even used to be able to move the plastic lid to do it, think it was just a kamikaze! Any way I knew it's antic so always left a book on the lid until one day I forgot. I went out on the razzle with the lads and got back in at silly-o'clock to find a bone dry rock hard common on my bedroom floor, I was gutted. So having had a few too many I threw him back in the tank and crashed out. Got up the next day and the bloody thing was swimming around 🤔
Hardy things carp are. Needless to say that I moved him onto a neighbours pond where he might even still be to this day. My advice, dig a pond if you want carp 👍
Are you sure?

This action cannot be undone.

Yes, continue
