Is Creeping Jenny a Good Plant for Neolamprologus Similis?

Reviewed by Guidarium Editorial DeskUpdated May 6, 2026
Not Recommended

Creeping Jenny is not recommended for Neolamprologus Similis. The issue is practical, not cosmetic: neolamprologus Similis is likely to uproot this plant while digging through the substrate.

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.

Overall fit

68/100

The fish is likely to outgrow, uproot, or out-pressure the plant.

Water match

Workable overlap

Shared range: 24-26°C, pH 7.8-8, 10-15 dGH.

Plant pressure

High

Neolamprologus Similis may chew, uproot, or stress this plant.

Layout value

Moderate cover

Creeping Jenny helps with breaks lines of sight and good refuge for fry.

Shared Tank Conditions

Creeping Jenny fits inside the water range normally used for Neolamprologus Similis. The shared window is about 24 to 26 °C, pH 7.8 to 8, and 10 to 15 dGH, which gives you enough room to aim for stable middle-ground conditions.

Both do best with moderate flow, so circulation does not need to be split into competing zones.

Both are suited to freshwater, so salinity does not add an extra planning problem.

Fish Pressure and Plant Resilience

Neolamprologus Similis puts heavy pressure on plants, so this species is likely to be chewed, uprooted, or stressed in day-to-day use.

Creeping Jenny has moderate cover density, low uproot resistance, and standard leaves. It can also help with breaking up sight lines and fry refuge.

The plant helps break up sight lines, which can soften territorial behaviour.

The limiting issue is neolamprologus Similis is likely to uproot this plant while digging through the substrate.

Layout Fit

Creeping Jenny is a stem plant usually used midground and background.

Neolamprologus Similis is an African cichlid, so the pairing works best when the planting style supports how that fish uses space and cover.

Creeping Jenny reaches about 40 cm tall by 5 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 Neolamprologus Similis 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: Neolamprologus Similis is likely to uproot this plant while digging through the substrate.

Best Use Case

Creeping Jenny is usually the wrong plant for Neolamprologus Similis 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.
