Jagermeister - tbh m8 I have no idea. I know this sounds highly irresponsible but I'm more interested in getting a tank first and think about fish after. My sister bought a sphere tank which magnifies the fish as it swims closer to the center - it's really relaxing and her fish is quite the character too - it's a Blue Oranda.
I also saw another funky tank in the corner of my eye when that Superman TV programme was on BBC2 - It was a glass tube on it's side - looked great.
I'm mainly interested in getting a fish cause it's quite a soothing pet to watch.
