Rusty Cichlid
Iodotropheus sprengerae Oliver & Loiselle, 1972
Also called Lavender Mbuna, Lavender Cichlid, Rusty

At a glance the quick version
Looks how to spot one
Compact rock-dwelling mbuna
A medium-small mbuna in warm rusty brown, overlaid in mature males with a lavender-purple sheen.2
Personality what they are like
Among the gentlest mbuna. It can live with peaceful Malawi species such as Aulonocara and yellow labs, and several males can often share a tank.32
Daily activity how busy a day looks
Moderately active; it browses rocks in shallow water and needs hiding spots to retreat to.32
Grooming and care the hands-on bits
Hard, alkaline water with good filtration and regular partial water changes; give it plenty of caves so it is not crowded out by bolder fish.32
Home where they are happiest
Aquarium of at least about 90 x 30 cm (around 81 litres) for one male and females, larger for several males; rocks and caves, temperature 24-29 C, pH 7.5-8.8, hardness about 10-25 dGH.312
Food basics what goes in the bowl
Omnivore; feed plenty of vegetable food such as spirulina flakes and blanched spinach, plus small live or frozen foods like brine shrimp.32
Company who they like around
Keep in a group with females, alongside other calm Malawi cichlids.3
The story where it all began
Described in 1972 by Oliver and Loiselle, it is named after Kappy Sprenger, a California aquarist whose interest in the fish showed it was an undescribed species.21

Owner questions the things everyone asks
How often should I feed my Rusty Cichlid?
Feed small amounts once or twice a day. Furry Diary's starting plan is to feed daily, and it's best to give only what they can eat in a couple of minutes.32 Pet Wiki plan
What does a Rusty Cichlid eat, and what should it never eat?
They are omnivores and enjoy vegetable foods like spirulina flakes and blanched spinach, plus small live or frozen foods such as brine shrimp. Avoid any foods high in protein or fat, and never feed them anything that could harm their digestion; ask your vet for specific concerns.32
How much space does a Rusty Cichlid need?
An aquarium of at least about 90 x 30 cm (around 81 litres) is needed for one male and females, with larger space for several males. Provide plenty of rocks and caves for hiding.312
What temperature, light or water does a Rusty Cichlid need?
Keep the water temperature between 24-29°C, with a pH of 7.5-8.8 and hardness around 10-25 dGH. They need hard, alkaline water with good filtration and regular partial water changes.312
How often should I clean a Rusty Cichlid's home?
Furry Diary's starting plan suggests a weekly 25% water change, weekly glass cleaning, and a monthly filter rinse using old tank water. Regular cleaning keeps their water healthy. Pet Wiki plan
Can a Rusty Cichlid live with others?
Yes, they are among the gentlest mbuna and can live with peaceful Malawi species like Aulonocara and yellow labs. Keep them in a group with females and avoid aggressive tankmates.32
How long does a Rusty Cichlid live?
Their lifespan varies depending on care, but with proper conditions they can live several years. For specific estimates, ask a good breeder or an exotic-pet vet.
Can I handle a Rusty Cichlid?
It's best not to handle them; they are fish and stress easily. Use a net only when necessary, and always keep them in water to avoid injury.32
