Right now I'm facing the moral dilemma of possibly "ruining" my Amazon-themed tank by adding a group of clown loaches. In an ideal world I'd give them their own tank and keep a more "geographically correct" mix of fish in each tank, but the reality is they're one of my favourite fish and I chose the option of one big tank over several smaller ones, so if I want them I'm going to have to mix-and-match with my SA fish. My tank isn't a true biotope correct to one particular river, but I do prefer keeping fish of similar habitats from the same continent together. In terms of water they're completely compatible, they all prefer warm, soft water with good flow, but something in my brain keeps saying it's not right to mix the different nationalities. Guess that makes me a wee bit racist?!
