It will be 16ftlong 18inches high and 18 wide.

12mm double braced top and bottom.

You could do 16x2x2 in the same glass thickness.

I wanted it narrow because I was only going to keep smaller fish in it.
Anyway the question has become moot now, see my post 'Xingu tank in the living room'
Anyway CFC your pictures have disappeared and I have nothing to drool over now.

Wow, very cool.

Some updates, the tank now has water in and the filtration is running, just some aesthetics such as sand a few more pieces of bogwood and rocks to add and i'm ready for the first fish to go in.

The sump

The blue canister is filled with 15kg of alfagrog, water flows down through the black central tube and back up through the media before going back to the main sump

in action

the 3 blue trays contain another 15kg of alfagrog and are semi submerged in the sump so the top tray works as a wet/dry filter

and a few pictures of the near complete tank

Very exiting project

Thanks for sharing

What´s in the second photo from the bottom?

That is apperently a bannana root?

I found it in a reptile store and acording to the lable it is safe for tropical and marine aquariums so i thought it would make an intersting piece aside from the usual bogwood and vines. It is extreemly bouyant so i had to silicone it to the base of the tank to keep it down, which is a shame because if it proves to be lasting in an underwater enviroment i would like to have added some more but draining the tank would be too much trouble.

I like the banana root

The pictures are really small. Do you use dialup or some other kind of slow connection?

CFC · Post by **CFC** » 02 Nov 2007, 16:52

The pictures are small because i have linked them from another forum where i moderate, and because of the forums huge size and high traffic pictures have to be kept to below 300kb to avoid the server getting over loaded. I have tried picture hosting sites but find that they either refuse to let you link pictures or they remove the links after a while leaving threads with little boxes instead of pictures.

When i finish the tank and have some fish in i'll see if i can put up a decent sized picture.

Stange, I have a free account at photobucke.com, but none of my pics were deleted - not even after 3 years.

Perhaps it is a result of putting only a few pics ther, I'm still under 60(I like talking about fishes, not nescessarily showing them off)

I thought i would add some updates, the tank still isnt 100% finished as i havent had time to wash and add the substrate yet but its getting there.

A friend of mine in the tank, the light above the tank needed wiring in to the new consumer unit and he wanted to try his new underwater digi camera so he did both at the same time, the wet suit was just for show lol

some of the pictures he took while he was in there

Agenieosus polysticus

small Sorubim elongatus

a group shot

and one taken from outside the tank, still having problems with the glare from the walls

those are big fish

Hi CFC,
That looks very impressive. I wonder what kind of Brycon(*) you have? Also: aren't you afraid the Arowana will jump out or is the tank covered normally?

Or is it Acestorhynchus??

CFC · Post by **CFC** » 11 Nov 2007, 20:44

Not a brycon, its something much worse. Its a Salminus brasiliensis, known as the freshwater Dorado or River tiger. Not really a suitable aquarium fish at all but since it was already in the country and having already been given to a shop once as it had eaten the contents of someones community tank i felt it wasnt too bad to take it in and give it a decent sized home. Its still no where near enough space "if" the fish reaches full size but its better than a 6x2x2 or smaller which would have been where it would most likely have ended up.

The tank has a cover made from 3 corregated roofing sheet panels, the original idea was to have it open topped and build an acrylic frame around the tank to prevent jump outs but condensation was too much of a problem so the idea was scrapped.

Cool
I have a similar problem with glare on the front of my big tank. You cant see into the tank in the day. Yet another reason the groke room was a failure.
That is being rectified as we speak. I'm planning on taking longer than a week this time.
Still I got a pretty nice conservatory out of it though.
By the way how much did you pay for the insulation pannels if you don't mind me asking.
Matt.
