When it comes to choosing fish companions for a bichir, there are some species that can co-exist peacefully. Bichirs prefer slow moving water with plenty of hiding places, so peaceful bottom-dwellers such as Corydoras catfish and White Cloud Mountain minnows are good choices. Other suitable tankmates include many small livebearers such as guppies and platys, or larger non-aggressive cichlids like angelfish or gouramis. Avoid any fish that may nip at the bichir’s fins, such as mollies or fast swimming barbs. It is also important to choose tankmates of comparable size – while the occasional large meal won’t hurt the bichir, adding small fry will only result in them becoming dinner! Be sure to provide plenty of hiding spaces for both the bichir and their mates; cave structures should be plentiful enough to accommodate all inhabitants without overcrowding. Proper filtration is also essential for keeping healthy water conditions; an efficient filter should help keep ammonia levels down which will benefit both species. With careful consideration and planning ahead of time, having a thriving community aquarium featuring a happy bichir can be achieved!
