As a further question, what is the effect of supplying "natural" water conditions for fish which have been acclimated to other water, perhaps over several generations? For example, is there anything to be gained by reacclimating apistos or angels to quasi-Amazonian water when they have been born and raised in harder, more alkaline conditions? Rusty
