I'm guessing I'm in a relative minority with an unheated tank in the house (I don't mean chilled thanks for pointing that out!)

How many others are out there?

when u say cold u mean with out a heater or have a chiller during summer?

i have tanks with out heater. 1 X 2 foot, 1 X 1 foot and 5 foot turtle tank.

I have one 90litre Jebo in the spare room. Has a couple of calico fantails so that guests have something to stare at. :lol:

Thanks fishboi! Have edited my post to clarify.

Chillers would be Marine tanks? Would they be fresh or saltwater or can you have either? What temps does one normally keep chilled tanks at? (Just curious!)

Does the tanks in the garage count? I got my white cloud minnow tank unheated. Most of the time it doesn't even register on the temp strip on the side of the tank.

if it includes WCMM tanks then I have 6

all my Killies are in tanks with no heaters in them

I have a four foot native freshwater tank. They are very sensitive to it heating up over summer as they mostly live in shaded streams and rivers. it can get incredibly hot over summer! Has been cruddy weather here and the tank is 22 degrees).

I have a chiller after losing half my fish by going away for the weekend last summer, came home and the tank was 29 degrees!

The new house I have moved to is incredibly warm, so all 5 of my tropical tanks are without heaters. The gold fish tank is also without heater... I was going to go into natives after talking to Stella, but there is no way I would be able to do that now because I wouldnb't be able to keep the water temp down.

HI Becc4!

I was going to private message you, see how the plans for natives was going. Shame you have had to change your mind on them, but convienient not having those heaters sucking up your power now!

Even with a chiller it can get worrisome as the days warm up.

I have 8 unheated tanks in my fishroom. 5 x 2-footer and x small tanks. (Less than 1 foot) because of all of the other heated tanks in the room they sit between 18-24 degrees which my swordtails, WCMM, and Leopard fish all seem quite happy at.

Hi stella, i had a look at your tank pics. That is very cool doing a native tank. Is there much info available or it just guess work? Well done!

Smidey

Hi Smidey,

It is a lot of guesswork, there is very little out there specifically on keeping them in aquaria. I quickly realised I knew more about them than most people I had to ask...

THere are a few really interesting books on them, more the biology side, and a lot of scientific abstracts on the net, from which you can pull stuff to apply to the native tank. I am in the process of writing a guide to keeping them, not because I am an expert, but because there is nothing else out there. I know enough and an obsessive researcher 8)

There is an interesting overview of the species here: http://www.nzfreshwater.org/index_main.html

Ah someone like me, information junkies unite :lol: .

What do you use as a chiller, (brand, make etc) and what is the wattage?

I'm curious to know if the running costs would be the same as a tropical tank. You'd certainly be winning as far as lighting goes.

>What do you use as a chiller, (brand, make etc) and what is the wattage?

Aqua Medic: Titan 150

Power uptake: 190 watts

Cooling power: 180 watts

It does not have its own pump, so that is seperate.

I want to know too!

The damned chiller has been going constantly for the last week. I am freaking at what my power bill will be. Anyone know how to work these things out?

How is tropical lighting more expensive?

Tank has far too many power cords coming out of it....

power head 301

powerhead 201

chiller

chiller pump

transformer for chiller (wrong plug holes, I dunno, was off trademe)

lighthood (2foot 2tube)

All for a 4ft/220lt tank.... sigh, at least the fish love the current!

And at least the fish are free! The tank etc took up a big chunk of dividing property in my recent breakup. Fish keeping is not cheap!!

Stella

i dont own a heater,so all my tanks are cold

I have 48 tanks that i am runing as cold water tanks

Hi, Dennis,

What kind of fish do you have in them?

many goldfish and axolotls

whitebait and corys and other things

What is the lowerst temperature cories can stand?

It seems like usually they are not regarded as cold water species.

i got a three foot tank with two large gold fish during winter it gets below 18 its got bn cats also some plates and cories aswell the tank being run for years with them in it.so some trop/fish can handel colder tanks.i did a lot of research alsothere are other fish that will handel the colder water;in my turtel pone ive got bn cats in there they in there year round.{outside}

I had there tanks they in go down to about 7 or 8 c some i have had in there for about 5 year now i have about 20 all peppred corys

Hi there, I have a 143 litre unheated tank at home with Fantail Goldfish and WCMM and a few Borneo suckers. Temp in the bedroom hovers around 17 degrees at the moment.
