There is an post on loaches.com, search for breeding loaches, where a Martin Thoene posted an article from a cory forum about breeding difficult spawners. It outlines how to simulate the end of the dry season to the rainny season. I am moving 4 red tail loaches, modesta, into a 50 gal to try this. Was to do this a month ago but got busy, two of the females are carrying eggs so it has to be done soon.
If anybody has any luck triggering the spawing of loaches posting the sucess would help others.
