Re: apisto specialization

[Bob Wiltshire <apistobob@yahoo.com>]

Gary,

The toughest species I have kept has to be A. iniridae. The ones I
have worked with were wild and required 0 hardness and pH of no more
than 4.0 for the eggs to develop.

I worked with them a long time gradually lowering the pH with each
spawn. At about 4.5 I got the first signs of fertile eggs - a few
larval fry. From there down I gradually got better results. I even
spawned them successfully at 3.5.

Needless to say, at these extremes it is very difficult to manage the
water.

For the most part I have found that wild apistos are fairly easy if
you give them what they need.
