I have a massive fish tank, with a few coldwater fish in, working filter, great quality of water, clean gravel weekly along with 20% water change.
What creatures can I add to the tank to make it look more interesting? Like, snails, crabs, plecs? Anything would be helpful!
Thanks :)

Recently bought a fish tank for coldwater fish. set it up with filter etc and added a solution that came with the tank. I’ve had fish before and this has never happened. But for some reason, the water is cloudy. Why is this? Is it just to much oxygen in the water?
the fish aren’t even in the tank yet … they’re non-existant! so why is the water cloudy? its clean ! … ??

My step-sister wants an aquarium. For some reason she INSISTS on them beings coldwater fish. Can someone please give me a list of coldwater fish besides goldfish, as her tank is only twenty five gallons and she wants more than one or two fish.

I hope I’m asking for the right thing, I mean an unheated fish tank standing inside my house lol, coldwater yeah?

If possible what are good prices for those fish

COuld maybe 2 goldfish live in their?

Aquarium Water Change
I am going to buy a bigger aquarium than the coldwater fish tank i have at the moment.
Can the water from my current aquarium be transfered into my new tank mixing it with new water?
Or will i need to do a new nitrogen cycle for it?
Just to let you know as well that i have had the fish in my current tank for just over a year. Thanks
