I'm into Tropical, fish from the Amazon Region, as the guy that helped me setup my tank a few years ago lived in that region, so he was very well clued up on the fish ect
My Partner has tried to stray from my original theme, she introduced what she described as "LOVELY COLOURFUL FISH" when I wasnt there, I HATE GUPPIES!
Thankfully there is only one left now, and whilst im tempted to say it must have died in the night, I have for now held my net away LOL
