Is Spade-leaf Anubias a Good Plant for Thinbar Datnoid?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Strong Fit

Spade-leaf Anubias is a strong fit for Thinbar Datnoid. The shared water window is realistic, and the plant has enough structure or resilience to be useful in a tank built around this fish. Fish pressure is low, so the plant can be judged mostly on water match, cover value, and layout role.

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

94/100

The plant and fish suit each other well.

Water match

Workable overlap

Shared range: 24-28°C, pH 6.5-7.5, 5-15 dGH.

Plant pressure

Low

Thinbar Datnoid is not flagged as unusually hard on this plant.

Layout value

Low cover

Spade-leaf Anubias helps with breaks lines of sight, useful spawning site, good grazing surface, and good refuge for shrimp.

Shared Tank Conditions

Spade-leaf Anubias fits inside the water range normally used for Thinbar Datnoid. The shared window is about 24 to 28 °C, pH 6.5 to 7.5, and 5 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.

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

Thinbar Datnoid does not put unusual pressure on this plant compared with harder fish-plant combinations.

Spade-leaf Anubias has low cover density, high uproot resistance, and tough / leathery leaves. It can also help with breaking up sight lines, spawning sites, grazing surfaces, and shrimp refuge.

It gives Thinbar Datnoid useful visual shelter and line-of-sight breaks.

The point to watch is thinbar Datnoid often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.

Layout Fit

Spade-leaf Anubias is a rhizome / epiphyte plant usually used midground, background, and attached to hardscape.

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

Spade-leaf Anubias reaches about 45 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, spawning sites, grazing surfaces, and shrimp refuge. Place it where Thinbar Datnoid can actually use that structure instead of hiding the plant where it cannot do much.

Practical Recommendation

This is a sensible planted-tank choice for Thinbar Datnoid, especially when you want the plant to do real work as cover, sight-line structure, or habitat detail.

The decision should center on this signal: Thinbar Datnoid often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.

Best Use Case

Spade-leaf Anubias is a strong choice for Thinbar Datnoid when you want the plant to do real work in the tank, not just survive in the background. The pairing tends to perform best when the plant's cover, resilience, or placement naturally supports how the fish moves, hides, or claims space.
