Custom fish tank

[Lots of shrimplets]

Hi, 

Can any one help me I'm looking to buy or have custom built a tank of 900mmx300mmx300mm. I'm in the UK, Midlands area. Its almost a US 20gallon long. But the UK seem to want taller tanks? I need it to fit in a alcove in my lounge. Planning to breed cpd in it. Any help appreciated.

I don't know of any myself but I put custom aquariums in search engine and a few came up but how much are you willing to spend as they were insanely expensive, around £1k?

As you already have MTS, how about 2 of these if you have enough room, including all the workings?

Or this would fit but give you a little room one or both sides

Anything bigger, as you say will be taller normally?
