It costs £50 on the water bill every time he does a water change, and things are really tight at the moment for them, not so much with baby stuff etc, they have all that already, just with another mouth to feed its gonna be a struggle, i love it and so does he, but needs must
That water bill is ridiculous, but it's totally besides the point. Buyers don't care whether he's spent £100's on a tank (and let's face it, a lot of us do

) and justifying the over inflated asking price by saying he's got a baby on the way, just doesn't make any difference. That's like some advertising a car and saying "I've added an extra grand on as we're skint at the moment and could do with the extra cash".
I used to work for a motor insurance company on the modified car section, and it always made me laugh when I asked the value of the vehicle and they'd take a deep breath then start listing all the things they'd replaced and what they paid for them. "Well the alloys are worth £1,000 and the exhaust was £500, so that's an extra £1,500". Erm, no, it isn't. Sorry I digress!
Anyway, I know this isn't your tank, but I had to laugh when I saw the asking price and then read that it had damage, got a load of bunged up holes in the glass and a DIY job cabinet!!! He seriously needs to look at what people can buy brand new tanks for. He'd do better listing the equipment separately as well.
I was considering getting a 2nd hand 4ft tank, but was just not willing to pay the silly prices people expect for second hand tanks, I'd rather pay the extra £100 or so and get to choose what cabinet effect I want and what colour sillicone I want etc. Some idiot was selling a 4ft tank with a red tail cat fish, oscars etc in, and said on the listing it's the buyer's responsibility to empty the tank!

I asked his reserve and it was £250

IMO he should be shot for keeping a red tail cat in his tank anyway, but that's another rant.
Good luck to them with the baby! Keep the tank and let baby watch it! I have a newborn and got 3 tanks already, 2 more coming Friday, and he loves watching the fish already.
