Amazing Fish tanks

[Sharefish]

Not sure if these are cruel fish tanks. I think should be ok since its more space for the fishes.

The first one am sure many of you guys here can DIY. Its a highway between two fish tanks and that is why the fishes swim up in the first pic..hehe..the second one I think its diff to DIY and you will have to buy it. Its nice though if you have lots of space.
