Bolivian Ram
Mikrogeophagus altispinosus
Also known as: butterfly ram
Tougher than the German blue ram and more community-compatible. Tolerates neutral water and slightly cooler temperatures, and survives occasional nitrate spikes.

Checked against several solid care sources that mostly agree. Numbers here are a careful starting point. Your tap water, tank size, and habits decide the rest. How we evaluate.
Best for: Planted community tanks 100–200L at 24–27 °C with sand substrate and peaceful mid-water shoals above.
Avoid if: You keep other cichlids at the same territory level, your substrate is sharp gravel, or your tank runs below 22 °C.
Common mistakeParking a single bolivian ram in an empty planted tank is how keepers invent a skittish, dull fish that never colours. Without a pair bond or calm midwater company it stress-mopes on one rock. Plan a pair or a settled dither school in at least 110L — not a lone ‘feature cichlid’ in 60L.
Top things that go wrong
- Shrimp & snails. Cherry shrimp and other dwarfs can coexist with peaceful small fish; baby shrimp are food for almost anything that finds them.
What most shops don't tell you
- 1.Myth: a single bolivian ram is a finished peaceful community centrepiece for any 60L kit. Reality: loners fade and hide without a pair or calm dither — they need footprint, softish water, and social context, not an empty planted show tank.
- 2.Sticking a single bolivian in a 60L community. A loner stress-mopes around one rock and never colours up.
- 3.Treating it like a tap-water community fish and skipping weekly nitrate checks. The fade-and-pinhole sequence starts above 30 ppm.
- 4.Keep as a pair or harem with line-of-sight breaks. Avoid hard alkaline Rift Lake mixes.
About this species
Bolivian rams are dwarf cichlids from the Mamoré basin, stockier and more tolerant of neutral hard tap water than the German blue. A pair will pick a flat rock or root and defend the patch around it, showing orange and blue once they settle.

Example setups
Starting points only. Run the pair checker for every fish you add.
Rough 110L+ layout: one calm centrepiece, 8–12 small tetras/rasboras, 6–8 corydoras-type bottom fish — verify every name in the pair checker before buying.
Safer directions include: Dwarf Gourami, Harlequin Rasbora.
Avoid “one of everything” baskets — Bolivian Ram belongs in a plan built around territory, line-of-sight breaks, and matched water chemistry.

Behaviour and temperament
Bolivian rams are peaceful dwarf cichlids that stay calmer as a pair with midwater schoolers. They are not aggressive community wreckers, but a loner looks ‘failed’ when it never colours. Stress shows as rock-hugging and fade when nitrates climb or company is missing.
What sets them off
- Sudden crowding
- Poor water quality
Fin nipping: Not a habitual fin-nipper; stressed or crowded individuals can still test fins.
Predation: Not a predator toward similarly sized community fish; fry and dwarf shrimp are still fair game for most species.
Territory: Holds a patch (cave, corner, or surface). Break sight lines so neighbours can pass.
Planted tanks: excellent — easy plant ideas
In the glass: typical and warning signs
- A pair works open sand and low structure while dither holds midwater.
- Mild courtship and gravel-kissing are normal ownership before fry.
- A dull loner on one rock usually means company and footprint failed first.
- Pinhole disease talk often starts after chronic high nitrate — test before blaming food brand.
- Spawn defence can push dither off the sand temporarily.
- Outside breeding they are usually calm with robust peaceful schoolers.
- Add a compatible partner or calm dither before rehoming a ‘broken’ loner.
- Break sight lines if spawn defence will not settle in a short tank.
Fish behaviour can vary between individuals and tank setups. Always observe new fish closely after introduction.
Water, food, and grouping
Hardness
soft
Diet
omnivore
Bolivian rams are small omnivore cichlids that take fine pellets and frozen foods near the sand once a pair settles. Midwater flake that never reaches them leaves a faded loner while tetras look fine. Offer sinking foods after lights soften, keep nitrates in check, and feed where the ram forages among open sand and low cover.
Shrimp & snails
Cherry shrimp and other dwarfs can coexist with peaceful small fish; baby shrimp are food for almost anything that finds them.
Keep at least 2, bought at the same time.
- Hold 24 to 28 °C steadily on a real thermometer, not the dial on the heater.
- Aim for pH 6 to 7.5 and a hardness you can re-test in two weeks. A one-time strip in the shop car park is not a water test.
- Footprint: short wide tanks and tall narrow tanks fish differently for the same volume. Match the tank shape to the swim pattern, not just the litre count.
- Tank volume meets or exceeds 110L published minimum for adults.
- You can stock at least 2 individuals (group welfare).
- Heater can hold 24–28°C without cooking cooler-water tank mates.

Plan with tools
Check mates as pairs first, then add this fish in the tank builder for the full stocking.
Filtration & heating
A 110L minimum tank needs a filter rated for at least 440L/hr turnover and a heater to hold 24–28°C reliably.

How Fishori evaluates compatibility (same logic as pair and tank tools).
- Seriously Fish. Mikrogeophagus altispinosus
Primary: aquarium size, water chemistry, behaviour, and compatibility (URL verified in upgrade script; recheck if site content changes).
- FishBase. Mikrogeophagus altispinosus
Secondary: taxonomy, distribution, and maximum length in nature; cross-check with aquarium import lines and measured tank parameters.
- Wikipedia. Mikrogeophagus altispinosus
Secondary: general species context; verify all husbandry numbers against a dedicated aquarium care sheet and your test kit, not a single table row.
Evidence notes
- The Seriously Fish profile for the binomial in this record was successfully reached as the primary aquarium reference.
- FishBase contributes natural-range size and habitat context. Translate those numbers through your heater, your water report, and your tank footprint before stocking.
- Wikipedia is only cited if the article URL returned OK. Use it for orientation, not as the only care sheet for an import.
- All compatibility text reflects typical hobby experience and the Fishori model. Individual fish, shop stress, and the order tank mates are added in can still defy a single-paragraph label.

Common questions about Bolivian Ram
- How big do Bolivian Ram get?
- Bolivian Ram adults reach about 8 cm. Shop fish look smaller; stock for the adult length.
- What size tank does Bolivian Ram need?
- 110L is the planning floor for adult swimming space and bioload. A 134L+ tank is the more comfortable long-term footprint. Length and depth matter as much as raw litres for active or territorial fish.
- Are Bolivian Ram aggressive?
- Bolivian rams are peaceful dwarf cichlids that stay calmer as a pair with midwater schoolers. They are not aggressive community wreckers, but a loner looks ‘failed’ when it never colours. Stress shows as rock-hugging and fade when nitrates climb or company is missing.
- What is the most common mistake with Bolivian Ram?
- Parking a single bolivian ram in an empty planted tank is how keepers invent a skittish, dull fish that never colours. Without a pair bond or calm midwater company it stress-mopes on one rock. Plan a pair or a settled dither school in at least 110L — not a lone ‘feature cichlid’ in 60L.
- What fish can live with Bolivian Ram?
- The Bolivian Ram profile lists Dwarf Gourami, Harlequin Rasbora among its safer pairings (engine-checked GOOD). Tiger Barb is conditional (CAUTION): workable only with the specific conditions on its pair page. Avoid African Cichlid, Jack Dempsey, Oscar (RISKY). Run the pair checker for your exact water and tank size before stocking.
