View Full Version : Carp for an aquarium?

10-02-2005, 16:02
Hi all,

Thinking about setting up a freshwater aquarium and putting in some tiny carp. I have access to a chap who knows his aquariums so am all up to speed regarding size of tank and that I need major filter throughput. None of that is a hassle.

My main question is where to get stock? What I would like to do is get some carp of around 4-6" in size. Pretty ones preferably. Are there any farms that would sell me such a small quantity of fish? Also would they take them back when they outgrow my tank or am I stuck to buying whatever the garden centres have and trying to get rid of them later in peoples back garden ponds?

i collected a few eggs from my local lake(hope that isant illegal!) but in my 3 foot tank they have only grown to about 3" in 18 months???

PM me, ask nicely and I'll sort you out with a few small fish...

Brought them from Hampshire carp hatcheries last year and I'm running out of space... I'll even let you choose them... http://www.rmcangling.co.uk/forum/images/graemlins/smile.gif

Linears or commons with the odd goshtie...

Dont mix them with any other fish and I'll take em back if need be..

Only trouble is the carp will get stunted growth after a couple of yrs and will need to be put in a sutible sized pond.

But are a joy to watch especialy when fed baked beans after sunday breaky mine went mad for them http://www.rmcangling.co.uk/forum/images/graemlins/smile.gif

Depends what you call stunted really, mine are in a 24*12*12 tank they aint gonna make 20lb but they are beautifully proportioned and no way could they be described as stunted. Everyone that see's them says how lovely they are and admires their scaling. These came from a lake at about 10mm long caught in a jam jar http://www.rmcangling.co.uk/forum/images/graemlins/grin.gif raised on fishmeal but now eat mini boilies and pellets.

11-02-2005, 09:35
They may be a ok for a short time while they are still juveniles but you certainly won't be able to keep carp long term in a tank that size, and they most certainly will get stunted over time (although death normally follows before you would notice)

That size tank will only just about be big enough for a few goldfish!

11-02-2005, 12:52
loads of oxgen needed to get them growing and feed them on the goldfish flake and nothing else they will grow like made. A good filter is also very important.

11-02-2005, 13:27
Thanks for the replies guys. I going to be using a 5foot by 2foot by 2 foot tank (when I track one down). My mate tells me that should be good for 8-10 carp for a while. I will not be mixing any other fish with them so hopefully I can keep them disease free (as long as they come that way). The only other thing I was told I needed was a good filtration system as carp are 'dirty' fish.

Looking forward to growing on me own beauties!

regarding filtration i would suggest that you don't go down the path of undergravel filter system

couple of large external cannister filters than can have different filter media and are very easy to clean

would also be careful with your choice of substrate and plants because as they get larger they do like to dig up the bottom of the tank

regarding food i would try to keep it varied - certainly some live bloodworm or daphnia are useful - i would avoid worms or maggots apart from a very ocassional treat - ditto trout pellets/boilies should be avoided

watch the location of your tank because close proximity to windows etc could cause you problems in the summer unless to intend to have the option of chilling the water

last but not least frequent water changes (make sure 'replacement ' water is conditioned)

11-02-2005, 15:46
Get the larger fluval the 404 should suffice for filtration, allow the filter mediums to mature, and use R/O water, this is available from good outlets, save much heartache from the off and with weekly water changes...enjoy.

11-02-2005, 15:49
I've got 7 carp in a 6 foot tank, 2 ghosties, 1 plump near leather and 4 fully scaleds. they're between 4 and 7 inches. 2 big fluval filters and an air pump. they will eat whatever you give them, the more they eat, the bigger they get and you have to clean the filters regularly as they can [censored] for england!!
They like a boiley or two, trout pellets will cloud the water so I feed mine with sinking koi pellets or some catfish pellets which they love, plus the odd worm.
They'll be going in the pond, if I ever finish it!!

11-02-2005, 15:49
Hi im rather new to this forum but i think you bring an exelent point across. having carp in an aquarium is brillent.!!!!!!!!!!! http://www.rmcangling.co.uk/forum/images/graemlins/grin.gif

11-02-2005, 15:53
One other bit of advice (though I dodn't really think carp are suitable for anything other than short term in a tank) is to make sure they tank has a lid. Otherwise you'll be picking dried carp off the carpet in a morning

No point in using RO water, would just be a waste of time &amp; money.......carp will live just fine in dechlorinated tapwater whether its hard, soft, acid or alkaline!

11-02-2005, 16:19
One Fluval 404 will not hack the muck produced by carp, especially with that size tank. If at all possible, I would use a small pond filter raised above the tank, and fed by a large powerhead or pond pump - which may well even be cheaper. http://www.rmcangling.co.uk/forum/images/graemlins/grin.gif

11-02-2005, 16:20
stick your inlet pipe down u/g pipe and combine the 2 , and then pass the water through spray bar into seed tray filter ( placed on top of tank ) = 3 filters from 1 pump . simple , low maintenance , the more filtration and agitation the easier to keep any speceis

11-02-2005, 16:24
Mine have flourished for nine years so far in my tank. 4.5' long x 3'high x 2'deep (I think thats the correct dimensions, haven't checked them for nine years http://www.rmcangling.co.uk/forum/images/graemlins/grin.gif) Approx 105gallons of water. As has been pointed out, they will only keep growing and growing if you keep feeding and feeding. Feed sensibly and they will not outgrow your tank (so long as it is a sensible size tank). Staple diet of mine is Aquarian gold fish flakes and like Jetski said occasional treats. Good filtration is a must. Set up properly there is no need for weekly water changes, every couple of months will suffice for partial changes. Plastic plants etc are a must. My carp are ghosties(4 of them, 1 looks like a normal mirror, 1 a white leather !), purchased at approx 2-3" long for about £1-3 each. They are all now about 9-11" long, superbly marked and perfectly proportioned.
Go for it mate and enjoy. http://www.rmcangling.co.uk/forum/images/graemlins/grin.gif

11 inches long at 9 years old, poor [censored] http://www.rmcangling.co.uk/forum/images/graemlins/smile.gif

Certainly not Simmo growth rates http://www.rmcangling.co.uk/forum/images/graemlins/smile.gif

11-02-2005, 16:40

sorry but got to disagree about water changes every couple of months

weekly is essential unless you are dealing with a huge tank - i would dread to think what your nitrate/nitrite levels are - anything probably apart from a carp would have gone belly up ages ago http://www.rmcangling.co.uk/forum/images/graemlins/blush.gif

they are extremely tolerant of poor water quality but i think you are being cruel to them - as singy said given their age and respective size something is well wrong

sorry mate but i tell it as i see it http://www.rmcangling.co.uk/forum/images/graemlins/grin.gif

Why tho Singy ??

The same could then be said for the millions of carp in all these ponds that never grow over that sort of size, that live happily in these ponds for years.

Certainly not, but a lot better looking. http://www.rmcangling.co.uk/forum/images/graemlins/laugh.gif (Also better proportioned and healthier lookin !! http://www.rmcangling.co.uk/forum/images/graemlins/wink.gif )

11-02-2005, 16:44
Levels are all fine and checked regularly thanks !

As said it is a fairly large tank - 18.5 stone empty (and concreted in http://www.rmcangling.co.uk/forum/images/graemlins/tongue.gif)

11-02-2005, 16:55
R/o water? come on these are carp not Marine fish, and if you do use r/o water please mix it 50/50 with normal water or add some r/o right to put some minerals back in it, as for a 24'' tank and feeding pellet and boillies, well thats mega cruel.

Only feed sparingly little and often, good quality koi/pond pellet (no trout,betain, marine pellet or bollies)
10-25% water change weekly with tap water of the same temperature stood over night heavily aireated to dissapate the chlorine etc.

Bigger the tank the better 80gal + and good large external canister filter capable of turnig the water volume over at least twice an hour = happy Carp http://www.rmcangling.co.uk/forum/images/graemlins/grin.gif http://www.rmcangling.co.uk/forum/images/graemlins/grin.gif

Dont just keep the Carp keep the water they live in and buy a test kit from a aquatic outlet and test for Ammonia and Nitrite regarly.

Still wanna keep Carp?? http://www.rmcangling.co.uk/forum/images/graemlins/confused.gif

11-02-2005, 17:49
Agreed Bean

Have two large external canister filters on mine for ease of cleaning and to make double sure.

Will up the water changes to weekly to make double sure again although my weekly tests come back spot on. http://www.rmcangling.co.uk/forum/images/graemlins/laugh.gif

11-02-2005, 18:24
my tank is starting to get cloudy. 4'x12"x18". 1 fully scaled 4", 1 linear 3"
what stops the clouding. i aint feeding pellets, only koi stiks and fish flakes?

11-02-2005, 18:57
Hi Bean,

Yeah stilll wanna keep carp. Understand the responsibility but should be easier than my other favourite, Sepia Officinalis. Gonna have to know a lot more before I try a marine tank! (but have seen cuttlefish in a tank at the Portsmouth Sea Life Centre....they are just fantastic to watch!)

So has anyone got any photos? Would be nice to see your set-ups and your carp.

Must track down that tank....

PM for you mubo

11-02-2005, 19:56
Hi Duzzy,
I think its great you have an interest in keeping fish in an aquarium, and are willing to carry out all the responsabilty that comes with running an aquarium.
Not sure on the Cuttle fish though m8, not kept them so I cant advise on um, onlyadvice really is the more water you have the less fluctuations you are likely to get with water quality and temp etc so get the biggest tank you can fit in your designated area.

Top tip, when I kept Mallawi Chiclids I had to adere to a extremly high stocking level, this was due to there aggressive nature and high stocking stopped one being picked on constantly.
So I had my tank drilled (profesionally) at one end and a over flow pipe fitted.
Under this tank (6ft) inside the cabinate, I installed a 4 foot tank and turned it into a sump filter, this means what ever was pump from the sump (bottom 4 foot tank) went into the top tank and returned back to
the sump via gravity giving me much more gallonage and also great for placing heaters etc.

Good luck

And i hope you enjoy your fish keeping

11-02-2005, 21:04
ah - brings back memories of the malawi's - murderous little [censored] - yes you have the keep stocking levels high to stop them claiming territories - if they manage to claim territories you would be lucky to get away with more than three pairs in a six foot tank

and the worst of the lot were the mbuna - little and lethal http://www.rmcangling.co.uk/forum/images/graemlins/shocked.gif

have kept quite a few different species - mudskippers were very entertaining

marine were my last venture but done correctly in a large system inc pre mix/heat chamber - auto drain off and all plumbed into the mains was very expensive (sorry forgot the generator in case of long term power cuts) - also getting decent livestock was becoming harder and harder - that bloody film nemo had a lot to answer for http://www.rmcangling.co.uk/forum/images/graemlins/mad.gif

great hobby but very time consuming - holidays were a problem because you could not trust anyone else to feed them correctly

11-02-2005, 21:30
Thats the [censored], Mbuna, probably the most colourful and cute of all freshwater fish, very close to marine, but very territorial, alot of work with 25% water changes once a week etc and diet of spiralina and frozen gamma food packs.
Very enjoyable hobby but like you say difficult to give them the time they need.

I only run a large pond nowerdays with Carp in. http://www.rmcangling.co.uk/forum/images/graemlins/cool.gif http://www.rmcangling.co.uk/forum/images/graemlins/cool.gif
