I took September 11 the whole tank (and last two snails lay eggs too)
in the room with the constant temperature 20°C (68°F).
I measured a water's temperature every day (from June 4th to September 11th) in
the morning and in the afternoon (usually at six a.m. and at six p.m.).
A thermal inertia was surprised in case so little tank. Lowest
temperature of water was 12°C (53.6°F) with the temperature of
air 5°C (41°F); highest temperature of water was 30°C
(86°F). A average fall in temperature was at 4°C (39.2°F),
maximum at 10.5°C (50.9°F), from the afternoon to the morning of
the second day.
The following photo (25 April 1999) shows sons/daughters and grandson/granddaughter of snails described in this article with two snails lay eggs:
Pomacea bridgesi all the way
And there are grandson and granddaughter Macropodus opercularis with their hard roe (25 April 1999):
First title my article was Ampullaria australis ... 1. June 1999 Harald Auer (Augsburg, Germany) wrote me:
Your outdoor breeding experiment of apple snails was a very good
idea and especially the data about egg hatching times etc. of the
snails. These data are usually not available. It is interesting
that they can withstand temp. about 17°C well.
I am in the "apple snail breeding business" myself, so I am
always interested in some substancial informations...
As I live in Augsburg in the same climate as yours it might be
interesting for me to put some apple snails out in summer, too.
At the moment I have a tank (20l) with water beetle and european
livebearing "Sumpfdeckelschnecken" (Viviparus spec.) there since
one week. We will see.
I have some common appe snails (Pomacea bridgesi). Please note
that this latin name is not the valid one and Ampullaria australis should no
longer be used. Unfortunately the Name Ampullarius is very
common and widely used in the hobby literature...
You can visit Harald Auer's page Odd Apple Snails in the Aquarium. He called me attention to Stijn Ghesquiere's
Apple snails page. Very interesting page with beatiful images of snails. You can enter this page by the click on its nice logo, too:
You can visit the funny Arty's Snail page or Patrick A. Timlin's page.
