Original description as Iodotropheus sprengerae: Breeding: Mouth-brooder: maternal, Mouth-brooder: promptocavus, Mouth-brooder: semelcavus.It takes about a day for all the territories to besettled so as long as the new fish arrives the same day, it will be on mostly equal footing withthe other fish." Either as 'rusty cichlid' or 'lavender cichlid', Iodotropheus sprengerae is an old favorite for mbuna beginners " I drain 25% of the water, rearrange the pots and rocks to form different shaped caves and then fillit back up and head out to the pet store. I find that water changing the tank the same day I buy fish works best. Whenever you add new fish to an existing stocked aquarium, always rearrange at least someof the tank decorations. Adding non-aggressive cichlids to a stocked tank is extremely difficult. Also try to buy the least aggressive species first so they have a chance to stake out a territory. When stocking your aquarium, try to buy all the fish of a given species at the same time. Sluggish fish or fish with injuries should be avoided. Often this behavior is a response to poor water quality or temperatureproblems. Fish at the top of the tank which are not begging for food should bea cause for concern. If the tank has no decorations, most of the fish should be in the lowerhalf of the tank. Cichlids all have very good (if nearsighted) vision and can see well outside their tank. When selecting your fish at the pet store, look for active fish which come to the front of thetank when you approach. Sometimes upsetting territories will shuffle the social pecking order and reduce competition between the males. When the fight to the death inevitably begins, either sell the less-desirable male or try rearranging all the tank decorations. However, it is virtually impossible to sex juvenile rift lake cichlids so most people end up with two males. Many rift lake cichlids will only tolerate one male of each species in the tank. I highly recommend The Cichlid Fishesof Lake Malawi, Africa as an excellent species reference. In the absence of such advice, you can purchase a good book or search the web for the species you want to buy. Your local pet store should be able to tell you how aggressive each species is.
The more distantly related the fish, the less likely they will behave aggressively towards one another. Also, aggression primarily occurs between fish of the same species. When selecting species, you should avoid keeping species of differing aggressiveness in a single tank. These mild-mannered species should be kept inpeaceful tanks with Tanganika cichlids or by themselves. johannii).The most mild-mannered species include Labidochromis caeruleus (Electric yellows) and Iodotropheus sprengerae (Rusty cichlids). The males will slowly but surely kill each other in territory battles.įortunately, there are numerous mid-aggressive species (eg: zebras, P. These fish areextremely difficult to keep as adults without breeding them to replenish the population. The most aggressive species of cichlids of Lake Malawi tend to be from the genus Melanochromis (eg: M. When selecting species for a single tank,care should be made to not select fish which will kill each other when they mature. However, some species are significantly more aggressive than others. All rift lake cichlids are more aggressive than tropical community fish.
