The lab acquired a pair of Paratilapia polleni "large spot", a rare cichlid from Madagascar. They must like their new home because the female already laid eggs. Unfortunately, as a safety precaution, the male and female were separated at the time by a solid acrylic barrier, so none of the eggs were fertilized. They are the most unusual cichlid eggs -- they do not stick to the substrate, but rather are attached to each other by a string-like filament. Very cool stuff!
