how may fish do you have in a 2 foot x 1 foot tank?

Question

i have 2 x 21/2" carp,
2 x 2" goldfish,
2 x blue goldfish 2 1/2"(not sure exact name),
1 x catfish 2 1/2",
3 x light cream colour 1 1/2"
3 x grey with red tip to tail and fin= 11/2"
any help with names and if it's alright to keep them together(i hope so)
and how many fish are suitable for this size tank?

the other measurement is 1 foot

Answer 1

We need the other dimension of the tank. It's 2" X 1' X ? That will help much.

Even without that info though, is sounds like you are ok... for the moment, BUT before long at all these fish will grow and you will need a larger tank or to return some of them. The goldfish and carp alone will be too much fish for most tanks made to be honest.

As for names on the fish, we will need even more info about them or better yet photos.

Give us that last tank dimension and we can help with what will be a proper number for the tank long term.

Answer 2

If your tank is a foot deep too, it is only a 15 gallon tank. This is a big problem because goldfish (carp too) are dirty fish and need 2 gallons, at the very minimum, per inch of fish.

That rule of thumb is for a filtered aquarium. If there is no filter, you need much more water per fish, up to 5 gallons per inch. And you need to be doing regular (weekly) partial (35-40%) water changes for goldfish.

Now the other problem... The other fish, light cream and grey with red tips on fins, sound like tropical fish. Tropicals need temps in the range of 72-80 degrees. If you are keeping them without a heater, you are stressing them and they will eventually succumb to disease or parasites as their immune system is compromised by the cold water.

If you are heating the tank for the tropicals, the goldfish will suffer because they are coldwater fish and need temps in the 60-65 degree range. There is no happy medium, one or the other will suffer... or both if you try to get the temp in between. It just won't work in the long run.

What you should do is buy a much larger tank (30 gallons would be good) and filter for the goldfish and a heater and filter for the smaller tank and the tropicals. They will all show you their thanks by being healthier, more colorful, more active and living much longer.

Answer 3

Your tank is already over crowded - Goldfish (no matter what anybody say's) arent tank fish. They're messy eaters and produce alot of waste which polutes the water quicker than most. Your best bet is finding a mate with a pond, giving them your goldfish, buying a heater and keeping tropical fish. You'll find these fish much easier to keep alive and happy (rather than alive and ill, which unfortunately is the state most Goldfish live in)

Edit.

MM, the hight of the tank wont change anything because hight of a fish tank doesnt change the surface area where essential gas exhange takes place. The increase in water volume is negligible.

Answer 4

i had a yellow goldfish, 2orange, a comet and 2 shbumpkins in a tank that wa s alitle biger in length with chinese language sucking loaches and cat fish, corys, saved at a temp of 24 ranges without issues yet after a month the fish pond became executed and the goldfish have been waiting to visit the pond. they're now extensive and to be uncomplicated once I positioned mine right into a tank they have been tiny fry, plenty smaller than you purchase in puppy shops. your tank is heavily over stocked on condition that goldfish strengthen particularly enormous and that they produce a number of waste additionally. make constructive the tank is planted with man made plant life as genuine ones will basically be desecrated by utilising the fish which you have and that they want places to hide additionally

Answer 5

It sounds like you have Koi and Goldfish and my concern would be the tank size. I think many of those are going to really outgrow this tank, and I'm surprised you are not seeing signs of distress at this point given the waste production by these fish. My input is this tank is overstocked at this point and I'd move up to a 55 gallon or 75 gallon to give these fish less stress potential as well as room to grow.

Answer 6

I use one of a couple of methods, either:

1cm of fish length per 12cm2 (twelve centimetres squared) of surface area

or

2" of fish per 1 (english) gallon of water.

Do both of them, and try to stick to the lower of the two, and definitely not above the higher.

For your tank, you should have about 60cm of fish (for any 1ft by 1ft tank, you should have no more than the length of the tank in fish length). Also, make sure non of the fish are above about 10cm ish for that tank (ie, to make up the 60cm, you shouldn't have two 30cm long oscars!)

Hope this helps

Answer 7

I was told from the pet store the best way to figure is 1 fish per gallon....I'm not really sure how this works though, we had a 55 gallon tank with 4 very large Oscars, I couldn't imaging having 55!
