I kept a rescued catfish in this for many years, unfortunately he passed on a few weeks ago.
Decided to no longer keep fish.. so the tank is surplus to requirements.
It's about 2.5 feet wide, 2 feet vertically, and 2 feet front to back.
Doesn't sound so big when you put it like that as cold dimensions but when you see the thing close up, omg it's huge.
It's not made of poxy thin glass, it's about a centimetre thick.
Must of cost an absolute packet when new, wouldn't know, I inherited it from a friend whose husband passed on a few years back.
Now then, not one to try and sell a man a pup unknowingly, it's not without it's downsides:
1. It's HEAVY - will need at least 2 beefy guys and a good-sized van to shift it. It will go through a standard doorway when you get it home but you need a clear unobstructed run all the way through to wherever you're putting it. No way you'll carry it through the house, the only way you'll shift it around inside is on one of those 2-wheel-trolly jobbies
I can supply one of the beefy guys and a suitable van and a trolly if necc.
2. It's dirty. Many years of fishkeeping leaves algae firmly attached to the glass.. whilst not scratched, the glass needs a real good clean. Not just a swill, you'd need to get right in there with a scourer for an hour or 2.
It should however, come up very clean and clear with a bit of elbow grease.
3. It leaks. Not fast, and not even fast enough to cause an appreciable damp patch underneath since the amount that seeps out, isn't enough to keep up with evaporation in a centrally heated house. But, it loses enough to need topping up every 2 or 3 weeks.
However it really needs all the silicone scraping out from the joints inside, and a bead of fresh silicone running round. You will need to use proper fishtank silicone rather than builders/bathroom silicone, since the latter contains fungicides that will kill fish.
As far as accessories go, there's:
- a water filter / pump unit.
- an air filter
- four fluorescent light units with tubes
- many assorted bits and bobs like thermometer, undergravel filter etc.
There *is* a wooden cabinet however, it's in exceedingly poor condition. Probably fixable if you're a DIY enthusiast with time available, but unless you're prepared to see it as a project it's probably a bit too far gone.
All in all this little lot is probably worth it if you really really want to get into fishkeeping 'on the cheap' and are willing to invest a good bit of time getting it all cleaned & fixed up. But if you have only a 'passing whim' interest I'd advise.. pass on it

If nobody jumps on it I'll be taking a sledgehammer to it & chucking it in a skip fairly soon. Which seems a shame, but to me it's a white elephant taking up space. The price I'm asking for it is, zero pence, anyone who can give it a home will be saving me the energy of swinging a hammer.
