13 Berghia, aiptasia eating nudibranchs, approximately 1/2 inch (stephanieae)

Description

These nudibranchs are an aquacultured strain maintained at M20 Reefs for 20 years.  This means they are hardy, adapted to marine aquaria and will devour your aiptasia.  These are egg laying adults approximately 1/2 inch, (3/8 to 5/8 inch).  They start laying eggs at this size.  This is the optimal size for aiptasia control because they eat the most aptasia at this size and because they lay the most eggs at this size.  The larger sizes are more expensive and less effective as their metabolism slows when they are larger and they lay less eggs and eat fewer aptasia. .  We ship only to continental US.  We ship all packages on Monday next day for a Tuesday delivery.  Notify us on Tuesday if there are any anomalies with the package.  Shipping is free.  All orders received by end of the day on Sunday time will ship on Monday unless other arrangements are made.
