Is Gillet's Anubias a Good Plant for Finger Fish?

Reviewed by Guidarium Editorial DeskUpdated May 4, 2026

Not Recommended

Gillet's Anubias is not recommended for Finger Fish. The issue is practical, not cosmetic: they are adapted to different water types.

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

56/100

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

Water match

Limited overlap

One or more core water ranges does not overlap cleanly.

Plant pressure

Moderate

Gillet's Anubias needs thoughtful placement and anchoring.

Layout value

Moderate cover

Gillet's Anubias helps with breaks lines of sight, good grazing surface, and useful spawning site.

Shared Tank Conditions

Gillet's Anubias and Finger Fish do not share a clean environmental window, so the pairing is already under pressure before behaviour is even considered.

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

Water type is a serious mismatch: Gillet's Anubias is listed for freshwater, while Finger Fish is listed for brackish water.

Fish Pressure and Plant Resilience

Finger Fish can still be rough on plants, but this pairing becomes more realistic when the plant is anchored well and used as part of a larger layout.

Gillet's Anubias has moderate cover density, high uproot resistance, and tough / leathery leaves. It can also help with breaking up sight lines, grazing surfaces, and spawning sites.

Gillet's Anubias is less tempting than softer, more palatable plants for known nibblers.

The limiting issue is they are adapted to different water types.

Layout Fit

Gillet's Anubias is a rhizome / epiphyte plant usually used midground, background, and attached to hardscape.

Finger Fish is an oddball fish, so the pairing works best when the planting style supports how that fish uses space and cover.

Gillet's Anubias reaches about 40 cm tall by 30 cm wide and is usually attached / wedged to hardscape with no substrate required. 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, grazing surfaces, and spawning sites. Place it where Finger 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: They are adapted to different water types.

Best Use Case

Gillet's Anubias is usually the wrong plant for Finger 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.
