Do clown loaches survive in a Malawi fish tank? I have read conflicting information on this from books and internet sites. I like their colors and after reading that they live well with malawis, I added 2 of them in my tank. However, in less than a week, they were dead. I initially thought they were just hiding behind the rocks as I also read that they don't like bright lights. I have been seeing them mixed in a Malawi tank in some aquarium shops.
