Wow thanks to all that said Hi! In my previous life I had a few tanks the primary one was holding a silver arowana. It was a good sized tank at 300 gallons but of course the arowana outgrew it, "he" went to my local aquarium that housed 3 other super sized versions. Now I have just set up a tank with some platties and mollys, it is a small tank at 100 gallons, i say it is mainly for my 6 year old but in reality it is all for me. I will see how it goes but i fully expect i will be buying another big tank in the near future and setting up with some other fish, its pretty difficult here in Czech as I dont speak the language so well and trying to find reputable places for fish is not so easy.
