Learn how to care for Bolivian Ramsâfrom tank setup and diet to lifespan, size, and tank mates. Expert tips and real-life insights to help your community tank thrive.
If youâve been looking for a peaceful, colorful cichlid that fits well in community tanks, the Bolivian Ram (often used as short for Bolivian Ram care) could be your perfect pick. Iâve kept these lively little fish for years, and Iâve seen how the right setup and attention can turn a shy ram into a thriving, vibrant aquarium star.
Short answer: Bolivian Ram care is doableâbut success comes from stable water conditions, a proper tank setup, and a balanced diet.
In this guide Iâll walk you through everything you need to know: tank setup, diet, lifespan, size, tank mates and types of Bolivian Ramsâplus my personal tips and experiences.
What Is the Bolivian Ram?
The Bolivian Ram (scientific name Mikrogeophagus altispinosus) is a dwarf cichlid native to Bolivia and Brazil. Itâs prized for its subtle yet rich colors, gentle temperament and manageable size in comparison to larger cichlids.
Short answer: A peaceful and colorful dwarf cichlid that works well in planted community tanks when cared for properly.
When I first introduced a pair into my setup, I watched them hide for a dayâbut by week two they were confidently sifting sand and settling at the front of the tank. That transition made me realise how much environment matters.
Size & Growth
Short answer: Bolivian Rams typically reach a size of about 3-4 inches (8-10 cm) in adulthood and mature at that size with correct care.
They are larger than many nano fish, but much smaller and more manageable than standard large cichlids. Because of their moderate size, they work well in tanks from ~20 gallons and up (depending on numbers).
In my experience: I started with young juveniles around 1âł and watched them grow steadily in a 30-gallon planted tankâwithin six months they were near full size and their colors deepened nicely.
Tank Setup: Bolivian Ram Tank Setup
Tank Size & Layout
Short answer: A minimum of 20 gallons is recommended for a pair; for a small group of Bolivian Rams or community setup go with 30 gallons or more.
They enjoy sifting substrate and exploring plants, so the more swimming space and hiding places you provide, the better.
In my tank I used a 30-gallon long layout with a deep sand bed and scattered rock/wood décor. That gave the rams room to explore and the tank looked great.
Substrate, DĂ©cor & Plants
Short answer: Fine sand or soft gravel, driftwood or rocks, and lush plants give your Bolivian Rams the environment they thrive in.
These fish love to sift substrate (itâs a natural behavior) so choose sand or very fine gravel. Incorporate flat stones for spawning and caves/hides for refuge.
I found that adding tall plants at the back and open space in the front helped my rams feel secure and show off better. They began using the flat rocks to âperchâ on and it became a highlight of the tank.
Water Parameters & Conditions
Short answer: Keep temperature around 73-78 °F (23-26 °C), pH around 6.0-7.5, and maintain low nitrates with gentle flow.
Bolivian Rams tolerate moderate hardness and somewhat neutral water, which makes them more adaptable than some cichlids. They appreciate stable conditions.
In my experience, when I stabilized the temperature and kept nitrates under 15 ppm, the ramsâ fins looked fuller, their behavior improved and they even began showing breeding behavior.
Diet & Feeding: Bolivian Ram Diet
Short answer: A varied omnivore diet including high-quality flakes or pellets, plus frozen/live foods, keeps Bolivian Rams healthy and colorful.
These fish eat both plant-based and protein-rich foods. For everyday feeding I used a sinking micro-pellet designed for dwarf cichlids (you might link an Amazon product). Twice a week I offered frozen brine shrimp or bloodworms to boost their color and growth.
I noticed a big difference when I switched from generic flakes to a mix of good pellets + frozen foods: the rams became more vibrant, more active at feeding and rarely hid.
Feeding Routine
Short answer: Feed small amounts 1-2 times per day and remove any uneaten food quickly to keep water quality high.
I feed mine morning and early evening. I give them what they consume in about two minutes and then stop. That approach prevents leftover food from fouling the tank.
In one instance, I forgot to remove excess food and soon the rams were hiding and my nitrates spiked. Lesson learned: better feeding routine = better fish health.
Tank Mates: Bolivian Ram Tank Mates
Short answer: Choose peaceful, similarly sized or slightly smaller fish that wonât outcompete or harass your Bolivian Rams.
Good companions include peaceful tetras, dwarf gouramis, corydoras, rasboras and some livebearers. These species share similar water needs and wonât intimidate the rams.
In my setup I paired two Bolivian Rams with a school of neons and some pygmy cories. The community felt balanced and the rams ended up being the focal pointâthey werenât stressed and often displayed at the front of the tank.
Tank Mates to Avoid
Avoid large aggressive cichlids, large catfish, or fast, abrasive fish that might stress or chase your rams. Their gentle temperament means they donât tolerate bullying.
Short answer: If a fish makes your rams hide or stop feeding, itâs not a good tank mate.
Types & Varieties of Bolivian Rams
Short answer: While the standard Bolivian Ram is the most common, there are color-enhanced or selectively bred strains. Care remains similar.
Youâll find variants like âRubyâ or âGoldenâ Bolivian Rams that show extra red or gold hues. The core needsâtank size, water parameters, dietâstay much the same.
When I selected mine, I went with standard coloration first to understand their behavior and care, then later added a color-bred pair once I felt comfortable.
Lifespan & Long-Term Care: Bolivian Ram Life Span
Short answer: With good care, Bolivian Rams live 3-4 years, sometimes even a bit longer when conditions are optimal.
Their lifespan depends a lot on water quality, diet, tank setup and community. Good packages = good lives.
In my long-term note: the pair of rams I had for two years were vibrant and activeânothing fancy, just consistent care. Reach the third year and they started showing subtle signs of agingâslower movementâbut still healthy and beautiful.
Health & Common Issues
Short answer: Many issues result from water instability, poor diet or stressânot the fishâs temperament.
Typical problems include:
- Fin rot or fungus if water quality is neglected.
- Stress hiding or loss of color when tank mates are aggressive or tank is overcrowded.
- Spawning aggression if a bonded pair defends territory and you havenât provided adequate space.
In my tank I once let a nitrate spike go unchecked and the rams began hiding. After a 40% water change, improved filtration and removal of some aggressive tank matesâthey bounced back in days. The takeaway: respond swiftly and correct root causes.
Personal Tips & Lessons Learned
Here are a few of my practical insights:
- Cycle the tank fully before adding Bolivian Ramsâthey donât like immature setups.
- Use a sand or fine gravel bedârams love to sift and explore.
- Add flat stones for natural behavior and spawning cues.
- Prioritise comfort: gentle flow, stable temperature and hiding places.
- Use a variety of diet: good pellets + frozen treats to get full coloration and vitality.
Short answer: Small refinements accumulate into big differences in health, color and behavior.
