Community tank, 30+ years running

I have posted photos of this tank before but took a new one yesterday.

The tank is about 360 litres, run by two internal filters; one Eheim and one unidentified The tank is heated by a Jäger heater.

This tank was bought second hand 1980, it was moved once in the early eighties and had a leak once also in the early eighties. Apart from those disturbances the tank has been running since.

I would probably have chosen a different background and substrate today but has it been there for that long it can be there for while more.

The inhabitants have changed; the main difference has been if there has been Discus or Angelfish inhabiting the tank.

The stocking today:
5 Angelfish
around 100 Cardinal tetras
aAround 20 Platys
3 Bristlenoses

I was saddened not to find the 10-15 year old Banjo catfish I spotted last year, I hope it’s still around in there though.

The interior has been the same, the small piece of bogwood in the middle once took up 1/3 of the tank and the Anubias originated from one plant.

I really, really regret not having taken one photo of it per year as it would have been very cool to have seen the evolution of the tank. This is something ill try to do with other tanks from now on and that could be an idea for fishkeepers in general.

It's a fake :-(( It's one of those pre-made paper backgrounds what were popular, I think it's a photo of bark on trees.

There were actually a few of those bark pieces lying around below the tank for awhile and they would have looked great but I have no idea how you could made them stay below water as they were very similar to cork. They ended going in with my snakes at the time instead.

30 years running! Wow what a accomplishment well done that's a lot of work and I'd say it's a record for a fishtank lifespan too, you should ring
Guinness World Records ;)

Thanks Mark! It's not my doing though. It's my fathers tank, we had it together when i was a kid but since I moved out 97 or 98 he has run it himself. I still have my way with it during Christmas times though :)

Here's the same in UV light:

Lovely story and lovely tank. Really like to see these tanks that have been around for a long time. Wonderful spectacle and the UV makes it "pop". Well done to both yourself and your dad

Cheers lads, appreciated.

Yeah the UV is great, it makes it look like a different tank. It's just the rampart algae growth it can create that keeps it from being used more.

Fantastic looking, 30yrs has me thinking no way still the same silicone has it been resealed a few times, or is it one of these old school hard ass tanks, ha, built like an Army Tank, great story too and brought back some great memories of my own father with his old dodgy tanks (that were resealed a number of times)

Where the tongue slips, it speaks the truth.

@Jeff: Thanks Jeff!

I have been thinking about the same myself. The tank was resealed once due to a leak which happened as a child (not me) was banging the corner of the tank with a hammer. Must be a hard ass tank.. I have resealed tanks below 5 years old several times now.

The tank has one of those aluminium frames and I wonder if this will lower the pressure on the silicone?

Another point is that the tank has not been moved or been left dry, I suspect that it would need to be resealed a.s.a.p . if it was to be moved or left standing dry for awhile.

Talking to my father about it he mentioned some tanks he had before without silicone, using something similar to putty or lute(?) for windows.

I remember those types of tanks with metal frames and sealed with glazing putty when my older brother used to keep fish. As you say, the key with them is not to let the putty dry, otherwise it comes off in chunks and the whole tank needs resealing. They weren't the best looking tanks and did weight almost a tonne :blush: , but were very sturdy.

Remember an old family friend having a tank sealed with glazing putty when I was a kid......
He might actually still be using it now, but its 20 years since I would have been in his house!!!!!

It's has been awhile lads, but I'm still lurking around :evil:

Just wanted to share the evolution of this tank:

File Attachment:


Changes:
- ca. 70 Cardinal tetras went missing!!! (I blame the Angels)
- x number of platies
+ 20 Black Widow Tetras
+ 4 Hypancistrus sp. L400 (my contribution)
+ 1 Cryptocoryne (thanks Bart)
+ 1 large birch branch

I saw the tank for two weeks during Christmas and the two pairs of angels were breeding as well as the Ancistrus sp. L100s. Nothing survives though which is a bit of a shame. Still hoping to see a a few Ancistrus survivors one day as it is a rare enough species.

Possible future changes that we have talked about (things go slow with this one):
* Adding a layer of fine sand at the front to cater for some Cories.
* More roots, especially at the top level, more shelter at the top would allow for some interesting options regarding stock.
* With the cats originating from the Xingu, one idea could be to slowly move towards that direction with other stock, then again half of the beauty of this tank is that it's an old fashioned community which I'm not sure that we want to mess with.
*Perhaps a top dwelling species of some sort, hatchet fish maybe?


Thanks for watching, hope everyone is keeping well out there!

Amazing Andreas to think of a tank running for that many years...a well established ecosystem for sure :) where is the tank btw? You said you saw it for 2 weeks at Xmas so I'm guessing it's at your folks house or something? Who does the water changes etc?

Cheers for the kind words everyone.

Yeah the tank is at my folks in Sweden. It's really my dads tank so he does the water changes, feedings etc.. I just get involved whenever I am over there so the credit is his.

It's well established indeed, and that thick layer of gravel must contain all sorts of goodies.
It actually requires very little maintenance compared to the amount of water changes I'm doing with my own tanks.

Keep your eyes peeled for the next update in January 2016

I'm not really sure Alan but my guess is that the angelfish Ickes them off.

The Black Widow Tetras are all there and seem to be thriwing so I think it's a size thing.

The tank would look great with small tetras so I think the plan is to just wait it out a few years

No matter how many times I see it, it's a setup that excites me and makes me want to do something that will stand the test of time like that!!!!!
However I don't think tanks built in recent years will last as long as that 1 has so far

Thanks for the reply Hammie! I'd say go for it, I can't see why a modern tank would not last as long, with TLC.

I have actually chased the two small tanks that I had as a kid, thinking of restarting one:)
