Oh haha! Thats quite old fish lore that is, I'm quite surprised you mentioned that.
I've paid for hardly anything for my new set-up thus far!
-Tank, from another mates attic
-Corydoras, free from work
-Large Angel fish, from customer, needed a new home due to move
-Flying fox, was ill, I took it in, treated it then took it home.
And all my ornaments and plants were written off or off our stockfile at work. I'm going to see how far I can this without paying a penny...
