- Hypsophrys nicaraguensis, Breeding pair in Lake Xiloá, [00:01:43]
Here's a short video of Hypsophrys nicaraguensis in its natural habitat in Laguna Xiloá, Nicaragua. The first part shows breeding pairs above the sandy substrate, where they dig caves to deposit their (non-adhesive) eggs. Note the many entrances into these caves. The second part shows pairs guarding their fry in the rocky habitat. Here they suffer from competition by Neetroplus nematopus, which has led to the altruistic behavior I showed in my other video.
- Parachromis managuensis, Hunting in Lake Apoyo, [00:02:00]
Michi Tobler (2005) reported on death feigning behavior in Parachromis friedrichsthalii. In this short video I show more or less the same type of behavior in Parachromis managuensis. Young specimens of this species in Laguna Apoyo, Nicaragua, act as if they are not well, showing a color pattern that is usually associated with frightened fish sitting on the rock-face, but suddenly jumping and trying to catch the sardinas swimming about by the zillions. Fascinating.
