Ok, so following on from my last post have spoken to boyfriend and we're thinking about creating an outdoor pond for 2 x tigernose and a red tail. How would we go about this, what size would be needed and any ideas re heating etc.

Have no idea what would be best for them but have the space to do it and as they won't really fit indoors hey, why not!!

Greenhouse would really help with the heating problem. Then you also have a greenhouse. For the three mentioned catfish, I would say minimum is 5-6' wide, 10-12' long, and 2-3' deep (2x4x1meters). That would be minimum and obviously would require massive filtration and an aggressive water change schedule.

This page has some photos of how someone built theirs - its not exactly an how to -but it should give you a good idea of what you will need to consider for space and building materials. I will look around and see if I can find some plans or material lists.

Good luck with this - if you are going to go with the redtail you should go as large as your space/budget allow.

With a fish that size the dimensions are more important than the gallons (the fish would be happier in a tank that was 12' X 12' and only a foot deep than something that was 8' X 8' X 8')

We were thinking of a pond type build, brick surround (like you see for koi, see link below for something a bit similar) approx 12' x 6' x 2' rather than an upright "tank like" structure. Think this would be ok? Any ideas as to plans, filtration/heating systems etc would be greatly appreciated. Thanks for the ideas and link already RobbieG!

This is going to be a definite project for us. We'll keep you updated during the build process and then might need help finding good fish. Obviously we're in the UK but are happy to pay import costs if necessary to ensure healthy happy fish.

I was thinking of buying the largest possible cattle trough at my local hardware store and putting plexiglass in as a window and painting the outside but I don't have the $$ at the moment to do so and it gets to cold here in Arkansas.

Here is a link for a DIY filter

Persons pond is 2500 gallons

How cold does it get in Portsmouth?

We think it probably gets down to 4 or 5 degrees a couple of times a year mid winter but seldom less than that. Summers anything from 16 to 28 but getting warmer each year!

Have been out and about today looking at pond. Thinking of doing the easy option and getting a preformed pond liner. Can get one about 3.6m x 2.4m x 0.75 meters, about 750. Didn't think this was too bad, any comments on size?

Gave me a start there - I was thinking farenheit

It may be pretty hard (expensive) to heat the pond without some type of enclosure. There are a lot of options for keeping it from freezing / warm enough for goldies - but your fish will want it much warmer than that.

It is definitely possible - but it may be more expensive than a small greenhouse or shed type thing and regular heating.

I'll keep looking though - a lot of people do what you are thinking of and someone has to have come up with a reasonable way to do it!

We have a small pond out in back of my house, probably around 250 gallons. We keep about 15 goldfish in there (they breed). I live in New Hampshire, USA, and it gets about 0 degrees Fahrenheit here, sometimes colder. Theres already ice over it. We used to take them out in the winter, but a few years back we had babies in there that we didn't catch the previous fall; they were perfectely fine. So now we keep them in there. We hot a pond de-icer from a farm supplier, and it keeps about a 1footx1foot are clear of ice, enough for gas exchange which is very important. Other than that, they're fine.

The trick is to stop feeding them when the water gets about 45 degrees.
