Hi all,

 Another fish that makes a very interesting conversation piece in the 
Biology room would be Riv. marmoratus/ocellatus.   I even brought these in 
for my teachers while I was in High School.

Dr Bruce Turner and Jonathan Turner have also created a great webpage for 
them with unbelievable bibliographies research data, and some great photos.  
An instant student research project.

Very hard to kill, and each fish is a near clone.   Often they are used in 
water polution experiments for this reason.  I have found them to be very 
long lived for more than 4 years and often in less than tollerable 
conditions for most fish in general.

Another interesting point is of course the fact that they are true 
hermaphrodites,  And males can be forced with cool water incubation of the 
eggs.   Eggs are large enough to readily see development with a simple 
magnifying glass and maybe just the naked eye.

they can be bred and maintained in less then 8 ounces of water. Will 
tolerate anything from Hypersaline to rain water.    In the wild they 
aestivate under logs and leaf litter.

What more can you ask for in a fish!!
Well color would have been a wellcome addition!!!  We will have to settle 
for character!!!

Oh by the way the form from Dan Griga (mexico?) is very prone to Primary 
males!! 25% in wild populations I have heard

God Bless, Lee "the Rivnut" Van Hyfte
