i had the same conversation with the owner of my lfs (a GOOD lfs) guppys used to be the first fish recomended to a beginner to tropical, they could even tolerate being kept in unheated tanks. but now because of the way they are bred and inbred to obtain the most desirable traits they become weaker and weaker, swordtails are now considered a better choice whereas once it was the other way around. the same can be said for some of the morphs of discus
What makes a "hardy" and "non-hardy" fish.
- Thread starter zacjeff
- Start date
yeh its funny how it all seems to have switched, such as discus once being a royal pain in the a** to keep but now i have heard they are becoming almost as easy as angels, with no dependance on RO water or other special considerations.

That's because when a fish is delicate, the utmost care for proper keeping and breeding are employed, and the fish gets stronger...
When fish are "hardy' all too often they are kept and bred in horrid conditions which weakens the strain...
It all makes sense to me
PS - I completely agree a hardy fish is a fish that can thrive in a wide variety of conditions... but as stated above, not giving them 'the right' conditions will reverse it's hardy nature...
