I was in a worldwide fish forum and came across a ? about keeping Rams in very hard, basic water (+8.0) . I said you should get some rift lake or CA cichlids but dont put a Ram in there. I got many responses saying Ph and GH are very overrated and once they are acclimated there will be no differance in lifespan, color or breeding. I dont even think they can breed under those parameters. Am I wrong. Ive always kept fish in water that is close to there indigenous waters-am I wasting my time?
I'm a big fan of keeping fish at similar values to what they're used to.
It doesn't mean that there aren't fish farms in Florida breeding neons in liquid rock
but having seen Florida neons vs wild neons
I know when I worked in a particular chain store where the pH ran about 7.8 -- we always had an awful time keeping neon tetras, black neon tetras, glowlight tetras, rams, and other truly soft water fish alive.
(basically - when I came in on Sunday, I was always shocked if any of the soft-water fish that had arrived on Tues were still alive)
I've got "tissue soft" water now -- and I have an awful time keeping livebearers happy (other than in the tanks that I put lots of crushed coral in).
I think that fish can be aclimated - lots of breeders breed discus at pH's above 7, including Jack Wattley, and "Discus Hans"
recomends his discus be kept at 7.0 BUT I wouldn't keep a random discus in 7.0 water -- only one that had been bred/raised in 7.0
I would agree with you 100% on the rams unless I knew for a fact that they had been hatched/raised in water with a high pH.
Having said all that - this probably won't get as much attention down in the Coldwater fish area.
How would you feel about starting a similar thread up in the water treatment area, hopefully it will get more attention up there.
Its new, its improved (its still a work-in-progress)
