Sisters act together – Cichlid sisters swim together in order to reach the goal

Many fish travel in shoals as a form of protection. But the exact shoaling patterns – who groups with whom – differ from species to species. A team of researchers from the Konrad Lorenz Institute of Ethology at the Vetmeduni Vienna studied cichlid fishes in Lake Tanganyika in central Africa. On their dives, the researchers observed that female fish dispersed longer distances from their natal grounds than males. To minimize risks and to secure the spread of their genetic information, females often swim together in a shoal with female siblings. Males, on the other hand, prefer shoaling with non-siblings. The results were recently published in the journal Oecologia.

My, How Your Colors Have Changed

We’ve all heard of corals morphing under different lighting. That piece that looks great in your buddy’s tank looks dull and washed out in yours. Or, you get that coral that does a complete 180. You see it at the store and it looks good, but once established in your aquarium, it turns into a gem. Well, we as a community do talk about coral color changes quite a bit, and we think we have found one of the most extreme examples of such an event

How To Pick Your First Seahorse: 12 Common Seahorse Species Explored

Any number of species of seahorses can be suitable for the right aquarium. Left to right: Hippocampus erectus, Hippocampus barbouri, Hippocampus reidi I’m often asked which species of seahorse aquarists should get for their first aquarium. This question may sound simple enough, but different species behave differently and have varying levels of care required. I’ve put together a list of the most commonly available species, their difficulty level and some additional notes.
