True, having worked in import rooms seeing what fish go through. Mass water changes, getting ship around in boxes.... People reckon discus are fickle, yet they survive all this. Sometimes not in great shape. but usually lol.
Lake Tangy's will get there soon, some species that have been in circulation already are what you would call tough. Most Lake malawi species have been in circulation for ages.
Use care with Wild caughts & German Bred new imports, if you are lucky enough to get your hands on some. I got some new into the country Electric Yellows last year, man they were touchy. Now days, slow fill up with the hose, no dramas.
But I know from raising altolamprologus species as an example. I have to be so cautious with the water quality. I have tried not to be as an experiment, with bad results. :roll: As in quicker water changes, using a higher % of water change as I got lazy....Yet the parents I can be a bit rougher with.
The majority of people can pretty much do what they want. Just know what you are keeping. You do have to be a little cautious, if wanting to breed Discus well, you do need soft water. Its the same with me with plants. Grow plants in the wrong ph, ie; roses. Sure they will grow, flower & such. But no where near as good as those kept in ideal conditions.
