cold water fish tank advice

Can anyone give me some advice on how to set up a cold water fish tank? I know its not just fill it up and put fish in it, what sort of things should i do. Any help would be appreciated. We have a tank an Aqua start 500 and a Maxi Aquq one internal filter.

fill it up with water, turn the filter on and leave it for a while. if you're only putting goldfish in it then just leave it for a week, live plants are also a good idea but don't get expensive ones from the pet shop as goldfish will eat most plants, ebay is the best place

leaving an empty tank run for a week is pointless...

that is just the name of the site... it covers ALL fishkeeping issues and the first page is SETTING UP and the forums are on the message board.. like I said

Put a bit of fish food into the tank to allow a bit of bacteria to grow inside the filter. Thats what I was told to do with a new tank.

Ive only got one fish left now and when it dies im having no more. Poor little thing... i feel awful waiting for it to die.

no it's not, the small amount of chlorine will dissapate in an open air tank. water conditioner/tank starter can be added but it's just a waste of money

that tank looks more suitable for tropical fish as goldfish prefer long tanks rather than tall tanks but as it's only 65l it probably wont make that much of a difference

on the box it says suitable for cold water, tropical and marine, who would have thought wanting a few gold fish would be so complicated, How many fish would you say would be suitable for that size tank?

ps Cheers to everyone who replied.

is there smaller fish that would be more suited to it?

if you know someone who can take them if they get too big, you would be ok with 4 small goldfish/shubunkins (most fish places will say you need a bigger tank for just one so lie when you purchase the fish) i currently have 5 small goldfish and 3 small shubunkins in a 130l tank but that's only because they'll be going in my 7000g pond once they get big enough

shubunkins are probably the other main cold water fish you can keep in a tank, they are colourful and will live happily with goldfish but they can get big after a few years.

mountain minnows will live in cold water, you'll need a few of them though as they like to live in groups of no less than 4 but they don't grow very big, i've had some in a tropical tank and they're nice little fish, they hang around the top of the tank.

gold barbs will also live quite happily in cold water tanks if the room tempterate isn't too low but again they like to be in groups so no less than 3/4, they can grow big after a few years but not as big as goldfish, you would be ok with several of them in your tank

i would start off with a couple of the 99p goldfish from pets at home, then add a couple of shubunkins after a few weeks if you like the look of them

goldfish are very hardy and will be ok in a tank that's only been left for a week, as mentioned above you can put a bit of food in the empty tank but it's not really needed if you're only putting goldfish in there, they'll start to poo the second they hit the water anyway


just to add to the "you would be ok with 4" bit, my mate has 8 goldfish in a tank not much bigger than yours, they've been living in there for just under a year now and aren't growing that big yet so it depends on how much space you want them to have, the more the better but obviously you don't want to sit there looking at a tank with 1 fish in

cheers DaveLister, your advice and info has been very helpful.

I'd ignore Dave's advice, he's talking **** !!

If you want to do this "properly", you'll need to fill the tank with dechlorinated water (use a dechlorinator such as Tetra Aquasafe).

You'll need to use this everytime you do a water change - putting "normal" tap water in the tank will kill off the good bacteria when it eventually builds up. Leaving the water for a few weeks will "eventually" disappate the chlorine, but you can't do this when you perform a water change each week (10% will do in that size tank).

You should also cycle your filter. Best way to start would be to get some "filter gunk" from someone who already has a tank set-up, or your fish shop should be able to provide some (speeds up cycle).

You can cycle the filter by adding some flake into an empty tank (or household Ammonia - not perfumed though). As the flake rots away, it will produce Ammonia. Eventually Ammonia eating bacteria will build up & get rid of the Ammonia & convert it to Nitrite. Again the Nitrite eating bscteria will build up & convert this to Nitrate.

Your Nitrates are then removed via water changes (or your plants will use this if you have any).

Ammonia & Nitrite will kill your fish. Nitrates are OK in low levels (less than 60ppm).

Most people (including your fish store) will probably tell you to just put your fish straight in as they are only 99p each & will cycle your filter for you (they will be in pain though as they are poisoned by the Ammonia/Nitrite & if they do survive, they will have vastly shortened life cycles).

Your choice

I'd buy a heater myself & keep some small tropical fish - they will look 10x better.

Good Luck

talking ****? i've kept fish this way for many years, still have several tropical tanks doing very well in my garage and they get topped up with warm water from the tap, not to mention the thousands of pounds worth koi/shubunkins/orfes/roach/golden orfes and goldfish in the pond

he's keeping a couple of goldfish probably, most of the above is not necessary, i've used water straight from the tap when ever i've done a partial water change, the chlorine level in the water that comes out of 9/10 taps isn't high enough to harm the fish. some of my 6-9lb koi started off in a tank set up in the way i have described, i've never had a fish die because i put it in a tank too early, they feed more or less straight away so they aren't in pain

The advice from ChrisUK is the advice we got from a specialist shop
aquaticfinatic.com/fis…htm
They advised to add chemicals to the tap water to remove the chloring and add bacteria then run for a week without fish. Introduce a single fish and after four weeks the tank may be ready for more but be careful about overstocking your tank.....

If you are recommending using tap water straight into a tank for fish, then you are indeed talking **** mate.

If you know anything about the Nitrogen Cycle you should know that Ammonia & Nitrite poisoning are lethal to fish & cause them immense pain - which is why you need to cycle the filter first & NEVER use water straight from the tap.

On top of the chlorine & other crap in the water, you WILL kill any bacteria that has built up in the filter if you do not treat it first with a dechlorinator.

Its bad enough people getting bad advise from Fish Shops without getting it from the internet as well.

OP, if your unsure, best to ask on a proper fish forum & not a shopping forum where anyone can post any old crap

I agree with Dave on this - adding the Bacteria start is no good as there are big concerns about the bacteria even being able to survive without a food source & without refrigeration.

If you do a fishless cycle, you can fully stock straight away (as the bacteria will be at a level that can support your entire stock - google it). If your going down the rotting flake route (or not bothering at all & just banging a fish in), then do this very slowly & leave a couple of weeks between fish additions.

i said leave it for a week before putting fish in, not throw fish straight into tap water, every fish that i've put in a tank that has been left for a week has started feeding within the first 5 minutes, fish wont eat if they are in pain, just like they don't feed when they are spawning

Come meet my 5 year old Goldfishes that are doing extremely well, and the amount of times I've replaced a whole outside tank with tap water and put them straight in throughout the years after I've left the water to sort its temps out for about 24hours, and not one has died and they are very healthy.

Sure, if you want to do the best you can, then do all you can do help them, but it's not always needed unless of extremely high levels of chlorine which is pretty rare tbh.

yes so have i, going by my experience all the rubbish they want you to throw in the tank before adding fish isn't needed, never lost a fish within the first 6 months of having a tank set up and like i said, they feed straight away and stressed fish wont feed, the only thing i've sometimes added is the coating you put in when adding new fish. if we're doing it by the book, the 65l tank in question isn't even big enough for 1 goldfish as they need 60-75 liters each

Agree with you ChrisUK

Fish produce ammonia by breathing and as waste.

Ammonia is poisonous to fish. A knowledge of the Nitrogen cycle helps here.

There are 2 types of autotrophs (bacteria) we want to grow in our filter and the first will convert ammonia into nitrate. This is also poisonous to fish.

The second autotrophs will convert the nitrite into nitrate and this is far less harmful to fish. We remove this nitrate by doing partial water changes each week to the aquarium.

There is an excellent article here that will guide you through the process.
