hey all, A friend of mine recently bought a small turquoise discus from panorama and has had it for about a month now, the thing is he's new to fishkeeping and still completely useless at it. "he battles to keep guppies and angels alive" My question to the discus guys is, are they really as sensitive as people make out? And I'v read on the net that you can get the more hybridized fish that are more tolerant to water conditions!? So if I were to start with discus what would you recommend and where would I get some quality fish like this? thanks phil..
