I'm in a bit of a predicament at the minute, when I started fish keeping in August '07, I got fish that looked nice and was active for my aquarium. Don't get me wrong is still love the danios, tiger barbs and my bristlenose but since visting TGM and looking at other people's tanks, I'm getting interested in replacing my fish and starting again with some fish which are more suited to a planted tank and some fish that a little bit more specialised. I don't really want to copy TGM's tanks but did fall in love with the pencilfish whilst I was there and was interested in harlequins when I got my tank in the first place. Just wondering if like trading your fish is a bad thing to do? Or is it something that people generally do when they re organise their tanks. The only problem is you wouldn't replace your dog when you painted your livingroom?!
