Re: maintaining Ph for fry?

Matt,

By now these juveniles should be able to handle
"more normal" water
conditions. Don't do massive water changes with
radically different water
values, however, but you can slowly change it to
slightly acid, moderately
hard, water over a period of a week or so. I don't
know what this will do
to the development of the fins, however. In A.
trifasciata, for example,
specimens raised in soft water develop higher
dorsal fin spines than do
specimens in harder water. Who knows, maybe the
same happens with Inca.
