How big should my tank be?
« on: August 29, 2010, 02:39:10 AM »

I'm really wanting to get 2 oranda goldfishs, hopefully one male and one female Wink. Anyways, how bit should the tank be? (no st*pid answers like 0 or something please) And what are the procedures I have to take before introducing the fish to the tank?

Oh yes, also. Can you tell me what I should look for when looking for a healthy "high-end" oranda?

WELCOME TO THE FORUM. Grin

Orandas can grow up to 8 - 12 inch. For the tanksize is rule of thumb minimum 10 gallons per fish, better more, or 2 litres per inch fish.

With the tank you will need - or better I recommend to have - a good filter, pump, airstone, peasized round gravel, live plants, AQ light, gravel siphon, nice centre piece ( please avoid sharp edges and small holes as the fish can get stuck...)

For the water I recommend conditioner to remove chlorine and chloramine from tap water, also beneficial bacteria to speed up the cycle and test kit for Ammonia, Nitrite, Nitrate and pH   ( like API Master Test Kit for freshwater fish )

Before adding fish you should set up the tank and let it cycle. I don't know if you are familiar with the Nitrogen Cycle. If you aren't let me know.

Basically if you are looking for healthy fish, take your time and visit all pet shops you can in your area. Look out for how clean the tanks are, how the fish are kept, are they wiggling at you when you look at them. Are the fins nice and not ripped, no spots or blotches on them like white and fuzzy or slimy things.
Are there tanks in quarantine, are dead or lethargig fish in there. Does the store smell clean... all those different things to look for...
AND very important. How knoledgeable is the staff.

A tricky question or suggestion you can test their knowledge: To go in there, telling you just filled your tank with water and you want to buy 1 neon tetra, 2 goldfish and 1 silver dollar.
If the staff grabs the fish net you know that person doesn't know anything or is only interested in making money but doesn't care if the customer will be unhappy facing trouble in the AQ and aslo doesn't care for fishes welfare. Why?

Neon Tetras are shoaling fish they should be kept min 6-8, better more. They also need different water conditions than goldfish.
The Silver Dollars are quite bossy and agressive, as they belong to the Piranjas.
So this combination of fish is not compatible at all and a knowledgeable staff immediately would explain that this cannot be sold to you, also that the tank should cycle first

Haha, smart. I know the general jist (gist...I dunno) of the nitrogen cycle. Wouldn't hurt getting to know it a bit more. Would a 75L tank be sufficient for the orandas?

I know you'd cover that Hanna. I'd go bigger but it also should just be ok. It's better to have about 40L per goldfish and I believe Oranda's can grow quite big. So the bigger the better Smiley

Yes, ok for 2 fishies Cheesy but as  Andrea said, bigger would be better.

here you can read about the nitrogen cycle Wink  (Link is not visible to guests. Please register to view.)

Correct me if I'm wrong, but technically - theoretically having 2 orandas in a 48L tank is still okay, but not ideal? Not that I'm planning on getting a 48L tank.

Theoretically it is wrong as in any good goldfish book would tell you this was wrong. However I believe maybe two Oranda fish could survive in this, but it is a bit of a gamble. There would be alot of built up of waste in a tank this small for two goldfish and a weaker one could die. There is also a higher risk of diseases which could also kill your fish. There would also be less oxygen and less room for swimming around which is what goldfish love to do Smiley I only have a 22L tank with one goldfish in it which is pretty much equal to what you are saying. However I am moving this fish out of there as soon as possible. It is alot more work for me as I have to keep a close eye on ammonia levels and the filter gets so dirty so quickly! The nitrates are currently at 40ppm which is the highest it can safely be and no matter what I do I can't lower this.

well, in this case go for a bigger one.
48 l is sort of ok, but not ideal. Also smaller tanks mean more work, bigger tanks mean plenty of room for the fishies to swim, thrive and be happy and much easier maintenance for you, so you can enjoy your fishes much better Wink

Andrea, how is the new tank set up and cycling going?

Did you try a 50% waterchange? this should get the Nitrates down to 20 ppm, then after 2 days another 50% one. Aslo did you try "Stability" from Seachem. It seems to be better than API Stresszyme. I recommend to get it for cycling your new tank and follow the instructions on the bottle. Same for Novaguin  Smiley

Tanks.

Would you recommend putting any live plants in the tank? If so, what kind of plants?

As complete kits the AquaOne 's are very popular here in Australia.
You must not worry about light, filtration, etc. as they come to be set up quick and easy.

If you go for the conventional tanks you will have to invest extra money in filter, light, pumps, etc.

If you like you can google for AquaOne, there you can see how they look like and how big the different models are.

I attach a pic of our small AquaOne. It is a 34 l only. We first had our Humphrey and Hepsiba in there ( lack of knowledge... Sad ) but they outgrew it in 2 month, so we got a 2nd hand conventional  150+ l tank for 100 bucks and restored it ( photos in " pictures and videos" ) for them.
I personally like the design of the AquaOne with the curved edges, all in one piece.  Wink

Oh yes, live plants are very good.
I only have a couple of artificial ones in the 150 l, just for a little colour, the rest is live ones: Hornworth, Ambulia, Elodea, Java Fern, Valisneria.

Do you think I should invest in an algae eating snale or fish?

Thanks for all the help. I'm off for the night.

I don't recommend snails, they multiply tooooo quick.
But goldfish are grazers too and with not too much light algae in a goldfish tank shouldn't be a too big problem.

BTW, I answered your question in your messages  Wink

Have a GOOD NITE  Wink

Hanna: You got it wrong there, it's important that it's not in this case. It's 2 liters per 1CM of fish, or 1 gallon per inch, but this is only to calculate tropicals. Goldfish absolutely (I repeat) absolutely need the 10 gallons each!!!

Novaguin: For these orandas, buy a 25-30 gallon (95-115 liters) tank, nothing less! A 100 liter would be just right Smiley By stocking the tank correctly from the beginning, you won't need to worry about water quality issues and your fish will grow big and strong! If you get something too small in the start, you'll have to upgrade soon, meaning that you wasted a lot of money Sad

They usually sell whole aquarium packages, with lighting, filtration and heating included Smiley I bought my 317 liter tank like that lately! Pretty good deal, as gravel was included as well Smiley If that's too expensive, you could look out for some second hand tanks! Just make sure that they're in good shape, no cracks, no leaks.

And you won't need anything to eat the algae, the goldfish will deal with that! And if you'll have lie plants, the plants will absorb all the nutrients in the water so there won't be anything left for the algae.

UUUPS, sorry for that... I think I never get it right with cm and inches, LOL, I apologize for that

Novaguin: Nossie is right.

Would you recommend Juwel tanks? Aquaone's are a bit out of my price range.

I've never heard of them but I just looked them up and they look good with the filter, media and heater included. Which one are you looking to get?

Hanna: I have tried to do big water changes but it is normally back at 40ppm Sad Guess it's alright cause that is still a safe level However I'm not stressing to much because Sunshine's moving out of that tank soon. Oh and I've already brought stresszyme, bummerrrrrr! Should be fine though.

Cannot see anything wrong with them either.

But hey, Novaguin, go to ebay.com.au and look for tanks. They are some nice ones around in Brisbane area. My husband and I just looked out of interest. You can have complete set ups and in case fish are included you can arrange with your nearest pet store to have them and you can have other things in change.

Well, the only place I've been to is Pet City. On their website, they have a  Juwel Starter tank which is 56L for $139. I realise it is definitely not big enough, but Juwel does seem a lot cheaper than AquaOnes.

I'm always a bit iffie when buying stuff on ebay. Main problem is I see the tank getting crushed, or the seller not being reliable. What should I type in? Most tanks that show up are in the $300+ range.

Novaguin: Look their website up, they have much bigger tanks on there. I didn't see any prices but I didn't have a good look.

Hanna: It does go down (sometimes) but goes back up again.

Did you read the message I send to you last night?

This is a very good price,  Cheesy, compared to what our 34l did cost; $180.
What does it include?

type in "aquarium" or " fish tank", refine the area. There should be less expensive ones too.
you also can look up on "tradingpost"

There should also hopefully be ones in your area which you could pick up instead of getting them sent to you, which would save you alot of money. Ebay is incredibly reliable in my experience, that is why it does such good business so I don't think there is an issue there. Just make sure you check out their feedback rating.

The Juwel tank includes: Tank, Light Unit 60cm, 1x15w Light Tube, Filter. The tropical one has a 50 watt heater for an extra $10. Doesn't specify what filter though.
