Re: [Killietalk] Spontaneous egg release/ Spawning triggers?

[Barry Cooper <bjc3 at centurytel_net>]

They're just telling you they are egg laden and ready to spawn. When 
collecting Nothos in the field it is common for the females to release 
eggs spontaneously. It is one of the reasons we have to change water in 
the bags. The decaying eggs foul the water.
