building a "big" Potamotrygon/SA Catfishes tank

Post by ElTofi »

Hi you all,

It seems I still have a few good ideas to apply, considering fishkeeping hobby :d

I intend to sell my 1600 liters (the one who homed the Pseuda's) to build a "big" concrete tank for Potamotrygon and bis Cats as Panaque or even bigger Pseudoplatystoma together with Cichla and Osteoglossum... I have this idea for a long time spinning around me from time to time... in 2005, building the house, I almost made it /:) and finally, I didn't dare :-??

This time, I'm on my way to do it...

here you can find a first simulation of what I have in mind


dimensions : 400x150x120 cm
netto volume : 6000 liters (more or less, considering I won't fill it till the top, because of the arowana)

This is just a first draft, of course. I need your inputs to help me in this project.

Arowana can jump 1-2 meters without any problem ;)

But it look's like a very nice project.

I know what you mean... I intend to build a 120 cm high for a real water height of 100 and install a kind of barrer upon it with plexiglass. The best would probably be a entire cover on the top of it all... :-\

You could put a screen iver the top. Like on screen porch doors.

That looks like a fantastic tank build. Best if luck can't wait to see the results!

The current "draft" I created this morning, waiting for the electrician (electrical updates to realize to implement this new tank) :

with 2 new glasses... this one would be 440 x 170 x 120 cm
Image

and in case I wouldn't be able to find a buyer for my 1600 liters, I eventually could recycle the front (or ground) glass. This one would "only" be 400 x 170 x 120 cm
Image

I will post a new "virtual scene" tonight...

Any specific catfish you want? When I take over the world, I'll have a tank at least 10 times the size of yours, with arowana, stingrays, Sailfin plecs and huge cichlids (Vieja and all large ones really). [That WILL happen ...] :YMPRAY: :YMDAYDREAM:
There should be a GCSE for catfish. Or a SATs paper, which is closer to me. At least we don't have to do Science.

Re: building a "big" Potamotrygon/SA Catfishes tank

a bit too early to freeze the population, but I'm thinking of :

- 4 Potamotrygon of the same specie (choice not frozen, but between P. leopoldi, P. henlei, P. schroederi "flower", P. "pearl"). I'd love to find bred specimen
- 5 Cichla "small type", for example C. monoculus or C. kelberi or C. ocellaris (exit C. temensis or T. orinocensis, much too big and agressive)
- 1 (2 ?) Osteoglossum ferreirai (black arowana)
- 6 Panaque sp L191, which are already growing in my 720 liters from a few months
- 1 Red Tail giant Catfish (Phractocephalus h.)

That's my dream as I dream it... I'll probably have to be more responsible... Even if this tank should be around 6'000 to 7'000 liters (around 1700 gallons), it's "only" a tank... not a river 8-|

A very impressive idea, I can only dream, looking forward to seeing it complete. What sort of filtration will you use?

What you can not see (yet) on this simulation is the "catwalk" I'm going to install above the tank, along the back wall. This catwalk will allow me to lay 2 "pond gravity filters" on it. The pumps will be settled on the bottom of the tank, and pulse the charged water into the filters... gravity will pour it back to the tank, after treatment.

Another idea comes slowly out of the muddy thinking cloud into my head : a vegetal wall, to cover it all... I could use Monstera or Spathyphyllum to clean my organic charged waters in addition to the filters...

Anyway, there will be an overflow and the tank will be filled in continuously with a flow still to evaluate.

Great Project:)

What do you think about scobiancistrus in your tank?
I dream to create such a big tank with scobiancistrus. But Panaque also would be great.
- 1 Red Tail giant Catfish (Phractocephalus h.)
For my point, Red Tail grows more then a meter, so it could be too big even for this tank. (I don't want to tell not to keep this catfish:)

I already have the Panaque... and I have bad experience with Scobiancistrus aureatus x( I know there's nothing to do with the specie... but...

And I must recognize that you're probably right for the Phracto... I know that... but... %-( Joking... I'm gonna see that later, when the tank will be built... probably not a so brilliant idea...

estheticaly, maybe b-) But considering size, there's nothing in common...

the German one is 105'000 liters
mine will be around 7'000 liters

see what I mean ? :((

Great tank!
I heard that large Panaques can harm stingrays cuite bad.... I read it in some book about fresh water stingrays....

Perhaps this is not a problem in such a big tank....

I'm building a 2400*1200*45 aquarium for stingrays and perhaps for some big pleco breeding,...


I like that you're back on track again! :YMPEACE:

L330 ate my marble motoro :( With lots of wood in the tank, you may have better luck in such a large tank, but be cautious. Maybe try a cheap ray first and see how they react.

Hi guys !

some news about this project... I recieved a lot of advices and ideas, and considering all this, I think the final project will be quite similar to this last simulation :

Image

530x160x110 cm of internal dimensions, so around 9'000 liters

The work should begin from end April with the remove of the 1600 liters. Then, I will order the electrical work and the building of the concrete tank should begin in early June. I'm considering one month for drying the bottom (with the heating system included), then building the front wall and drying during another month. Then I'll manage the 2 componants resin layer and finally, at the end of August, I'll manage the front glasses...

More or less, it should be ready to be filled in early September 2011...

and then... \M/

Looks good. I take it you have consulted someone with knowledge in structural engineering regarding the thickness of the concrete and the size of windows - to me, the piece between the windows seem pretty narrow, and would be a weak spot. But it's a long time since I studied engineering of that kind, and I didn't actually study building engineering at all - it was mainly metal constructions that I dealt with (and only simple ones - only so much you can learn in 2-3 hours per week over two years when you start from scratch).

Is the bar at the top over the windows structural, or simply decorative and protective of the glass top?

each part of the "front wall" is 50 cm long...

I took advice from profesionnals indeed, and a second advice from people who built such tanks on their own. I'm quite confident, as the concrete support front wall will be "armored" with steel bars, which will be bedded to a depth of 20 cm into the basement and 10 cm into the side walls.

as the height of the water column is "only" 110 cm, the glass taken on 4 sides and will be on the upper side of the tank, the thickness of 19 mm is confortably sufficient. And the bar above the glass will be structural, to have a 4 sides contact to glue the glass. Moreover, I will install a 70 cm Plexiglass balustrade above it, to avoid "jumping problems" with Arowana and Characidae.

all these points have been challenged... but I could have missed one... so feel free to ask and to challenge it !

a long Sunday afternoon... I make a bit of order in my late topics...

just to say that the project is running well... the 1600 liters has been removed (what a mess) and the basement with heater incorporated is done... next step : the front wall... I'll show you a few pictures these next days.
