Green Cabomba
Cabomba aquatica
Dusky Millions Fish
Phalloceros caudimaculatus
Quick Decision
A plant can be technically compatible with a fish and still fail in the actual tank if the fish digs, chews, needs denser cover, or uses a different part of the layout.
62/100
The fish is likely to outgrow, uproot, or out-pressure the plant.
Workable overlap
Shared range: 22-24°C, pH 7-7.2, 8-8 dGH.
High
Dusky Millions Fish may chew, uproot, or stress this plant.
High cover
Green Cabomba helps with breaks lines of sight and good refuge for fry.
Plant and Fish Fit Notes
Use these signals to decide whether the plant is doing useful work for the fish, or whether it is only surviving beside it.
Overlap: 22-24°C.
Overlap: pH 7-7.2.
Overlap: 8-8 dGH.
Flow expectations are close enough for one layout.
Plant pressure: High.
Shared Tank Conditions
Green Cabomba fits inside the water range normally used for Dusky Millions Fish. The shared window is about 22 to 24 °C, pH 7 to 7.2, and 8 to 8 dGH, which gives you enough room to aim for stable middle-ground conditions.
Both do best with gentle, low-flow water, so circulation does not need to be split into competing zones.
Water type can work if the tank stays in the shared part of freshwater and freshwater to lightly brackish water conditions.
Fish Pressure and Plant Resilience
Dusky Millions Fish puts heavy pressure on plants, so this species is likely to be chewed, uprooted, or stressed in day-to-day use.
Green Cabomba has high cover density, low uproot resistance, and delicate leaves. It can also help with breaking up sight lines and fry refuge.
This plant adds the denser cover that Dusky Millions Fish usually appreciates.
The limiting issue is dusky Millions Fish is likely to chew or tear this plant before it settles in.
Layout Fit
Green Cabomba is a stem plant usually used background.
Dusky Millions Fish is a livebearer, so the pairing works best when the planting style supports how that fish uses space and cover.
Green Cabomba reaches about 80 cm tall by 8 cm wide and is usually rooted in substrate with inert substrate is fine. That makes placement and anchoring more important than simply adding a larger bunch of stems or leaves.
In this pairing, the useful plant values are line-of-sight breaks and fry refuge. Place it where Dusky Millions Fish can actually use that structure instead of hiding the plant where it cannot do much.
Practical Recommendation
For most keepers, a tougher or better-matched plant is the smarter choice. If you still try it, test with a small amount first and be ready to move the plant before it is badly damaged.
The decision should center on this signal: Dusky Millions Fish is likely to chew or tear this plant before it settles in.
Best Use Case
Green Cabomba is usually the wrong plant for Dusky Millions Fish if your goal is a stable display tank. The issue is rarely one dramatic failure on day one; it is the steady mismatch between what the fish does in the scape and what the plant needs to stay attractive long term.
