At a glance the quick version
Looks how to spot one
Small, deep-bodied dwarf cichlid
A jewel-like dwarf cichlid with blue spangling, a yellow-gold head and a dark eye bar. Males have longer front rays on the dorsal fin, and females often show a pink belly patch.23
Personality what they are like
A peaceful little cichlid that forms pairs; males become territorial toward other males, especially while breeding.23
Daily activity how busy a day looks
Moderately active near the bottom, picking through the substrate for food.3
Grooming and care the hands-on bits
Needs warm, very clean, stable water. Small regular water changes of about 10-15 percent work better than large ones, and flow should be gentle. Best with calm, small schooling fish such as cardinal tetras.3
Home where they are happiest
Minimum 60 x 30 cm footprint (about 54 litres) for a pair. Water 27-30 C, pH roughly 5.0-7.0, soft water around 1-12 dH, with sand and some cover.13
Food basics what goes in the bowl
Sifts the bottom for food; offer live or frozen bloodworm, brine shrimp and daphnia plus good sinking pellets or granules.3
Company who they like around
Keep as a pair or in a small group in a larger tank; pairs claim a territory when breeding.13
The story where it all began
Myers and Harry described the species in 1948 as Apistogramma ramirezi, naming it after Venezuelan collector Manuel Vicente Ramirez. It has since become one of the best-known dwarf cichlids and is bred commercially in large numbers, with several colour strains.213

Owner questions the things everyone asks
How often should I feed my Blue Ram?
Feed your Blue Ram small amounts once or twice daily. Furry Diary's starting plan suggests feeding every day. Offer a variety of live or frozen foods and quality sinking pellets.3 Pet Wiki plan
What does a Blue Ram eat, and what should it never eat?
Blue Rams enjoy live or frozen bloodworm, brine shrimp and daphnia, plus good sinking pellets or granules. For foods to avoid, it varies by individual; ask your exotic-pet vet for a safe list.3
How much space does a Blue Ram need?
A pair of Blue Rams needs a tank with a minimum footprint of 60 x 30 cm, which is about 54 litres. Provide sand substrate and some cover for their comfort.13
What temperature, light or water does a Blue Ram need?
Keep the water temperature between 27-30°C, pH around 5.0-7.0, and soft water (1-12 dH). Lighting needs vary; consult a good breeder for specific recommendations.13
How often should I clean a Blue Ram's home?
Perform small regular water changes of about 10-15% weekly, and clean the glass weekly. Furry Diary's plan suggests a 25% water change each week and rinsing the filter monthly in old tank water.3 Pet Wiki plan
Can a Blue Ram live with others?
Blue Rams are peaceful and can live as a pair or in a small group in a larger tank. They do best with calm, small schooling fish like cardinal tetras, but males may become territorial during breeding.31
How long does a Blue Ram live?
The lifespan of a Blue Ram varies; ask your vet or a good breeder for typical expectations.
Can I handle a Blue Ram?
Handling is not recommended for fish; it can cause stress. If you need to move your Blue Ram, use a soft net and ask your vet for guidance.
