RD. (Neil) has contributed greatly over the years in the area of fish nutrition, health and maintenance. His work with others in the area of probiotics has been ground breaking in bringing the concept of competitive exclusion to the fore as a way to improve the overall health of the environment and as a means by which to proactively prevent negative health issues from becoming established in aquaria. RD. is a valued and respected member of MFK and I feel his contribution as such sould be recognized.
