I will sort of reply to both the emails about eriocalon together for
this. In answer to the first question about actually growing it I have
not done it yet either. However within ANGFA there are some very keen
plant nuts and I suggest that you contact Bruce hansen about it. He has
posted to this list before. If you live in melbourne try Neil Armstrong
or Ron Bowman, again within ANGFA. It is an ultra high light high temp
plant from what I have heard in the wild, ie it has been found in pools
of around the 40 degree celcius mark in full sun in shallow pools.
>Several people that I know have and all say that it is an annual.
Absolutely true I have not heard of anybody being able to keep this plant
more than a single season, unlike Ottelia alismoides which is supposed to
be an annual but I know of people with four year old plants.

The latest ANGFA Fishes of Sahul volume has an article on it by Neil
Armstrong who was among the fisrt of people to get it growing in captivity.

seataceum is supposed to be the only true aquatic in the genus and it is
from a tropical lattitude.

I am still awaiting my seed and instructions so I can not really compare

If anybody is interested in australian plants or fish a Rainbowfish
mailing list exists. The RML archive address is below which should
contain instructions on subscription anyway.
