Comets at the bottom corner of tank
« on: November 02, 2010, 09:04:09 PM »

Hi i am new to having fish as pets and have recently set up our tank according to the local pet store,  we than purchased four comets and placed them in the tank, the tank consists of filter/pump and gravel. Lateley they have been staying in the one spot, in the bottom right hand corner near the filter the filter is on it lowest setting, i read somewhere else that this may be because they fish are scared and some accessories ie rocks, plants etc may calm them. Could anyone please help. Thanking you in advance.  Smiley

Since your tank is relatively new, it probably hasn't done cycling yet.  The first thing you should check is the water parameters in the tank (ammonia, nitrite, nitrate and ph). Without knowing what your water parameters, it will be almost impossible to know what is the cause of the problem.  For example , if your ammonia reading is too high, it will stress the fish and they will not likely be swimming around very much.

If you don't have test kit , you can bring a sample of the tank water to a local pet shop and they will usually test it for you for free.

A good test kit you can buy is AP liquid master test kit.

Once you know the results from the water test, post them back here.

How long has the tank been running?

I set the tank up 3 days ago, i tested the PH and got that right (Neutral) i add other stuff the pet shop told me to add to kill chlorine and to add some salt chemical and another chemical i forget now. Its about a 17ltr tank.

17 litres is much, much, much too small for four goldfish unfortunately! Unless you get a bigger tank you are going to just have problem after problem and your fish will probably eventually die Sad Goldfish need about 40 litres per fish!! So you are either going to have to get a 160 litre or give all your goldfish away!!

Your tank is also definitely not cycled, it can take 4-6 weeks to cycle so what is happening is that your fish are being poisoned by their own waste. Please get your water tested, it is best to buy a test kit but if not you can take a sample of your water to the fish shop and they should do it for free or for a small fee. They aren't scared, goldfish are pretty brave Smiley

Water conditioner is good and necessary but it won't help the situation here. You will need to also buy some beneficial bacteria if you are for Australia which I guess you are, there is plenty of them out there so go ask at the pet shop. I use stress zyme by API. You will have to do water changes probably every day or every second day until your tank is cycled or nearly cycled. But test the water!! Plus 17 litres is so extremely small, I couldn't imagine having four fish in there even they are tiny they will grow big very soon.

I would turn the filter up a bit more too, goldfish love oxygen but not too high if they are sick.

Welcome australiancomet to the forum, lots of nice people here, all happy to help. So you're in Down Under too? Grin

But let's get started to solve your problems.
Nabi and Andrea covered the most important already.

1. The tank you've got is faaaaaaaaaar to small for 4 comets. You need min 10 gal per goldfish. They grow fast, they can reach up to 12 inch or a bit more. They also are very "messy" fish. This means they eat and are champs in pooping too, lol
This is why you need a bigger tank, a 3ft would be perfect. Enough water and space to swim, weekly maintenance with 50 % waterchanges ok.
2. You need other equipment towards your tank: a very good filter whcih turns at least 2-5 times the volume of the tank per hour, others recommend even 10-20 times. This will be full blast Cheesy. Then you will need an airstone to oxygenate the water and of course a pump.
3. Live plants. Not only that goldiel like to nibble on them like a salad snack, but they also use up nitrogens ( nitrate ) and produce oxygen during the day ( see Photosynthesis )

Now that your fishies are bottom sitting is a sign of distress which will lead to illness. Most times poor water quality is the reason for this. And if it is not acted on this matter the fish will be poisoned by their own waste and poorly die  Sad

Did the staff in the petshop inform you about the Nitrogen Cycle ? And that the tank must cycle before adding fish? And to add one fish, maximum 2 at the time? 4 fish at once are definitely too much bioload for the filter to manage.
At this stage your fish will poison themselves, especially in only 17l. ( which is even too less for 1 goldfish )

What you need to do to help your fish to survive and get better is the following:

Get yourself a bigger tank ASAP with filter and air supply ( look up on ebay, trading post, local forums... we do have quite a few here in Aussie... if you are interested let me know, please )

In the meantime 50% waterchanges EVERY single day. But please don't clean the filter down, let the beneficial bacteria settle.
Add waterconditioner like "Stability" from Seachem according to instructions. Add waterconditioner to remove chlorine and chloramine from tap water which are highly toxic to fish. Keep pH right, with this one it is most important that it does not fluctuate like a yoyo, at the same time a pH of about 7.0-7.2 keeps Ammonia less toxic.

Get the API freshwater test kit and keep track of Ammonia, Nitrite, Nitrate, pH.

Now, if you live in QLD, maybe @ the Sunshine Coast I can recommend a local supplier for the best waterconditioner going or even join our local "club" of fish crazy peeps.

DO you know about the Nitrogen Cycle? If not, let me know, I'll explain it to you and how everything connects together. Please don't hesitate to ask.

Thanks all for your comments, i have now purchased a larger tank, 120ltrs, probably stll too small for my commets!! But its a start. There is alot more involved to having fish than i first thought!!! For an update my commets are actually swimming around a bit more now i turned the pump up and added some scenery, they still prefer the one corner though, i will keep them in this tank until the larger tank has time to cycle. I am from Wagga down in NSW

Sounds good Smiley I don't remember if you bought the test kit yet, but you definitely should! Not only to keep the water quality nice in the current tank, but also to see how the cycling process goes with the new one! Smiley

I would get a 80 gallon tank. If you like to spoil your fish!

1 baby fantail = 5 gallon tank
1 adult fantail = 10 gallon tank

1 baby comet = 10 gallon tank
1 adult comet = 20 gallon tank

Or you could do the 1 goldfish per 10 gallons.
