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

62/100

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

Low

Green Spotted Puffer (Brackish) is not flagged as unusually hard on this plant.

Layout value

Moderate cover

Willisii helps with good refuge for shrimp, good grazing surface, and breaks lines of sight.

Shared Tank Conditions

Willisii and Green Spotted Puffer (Brackish) do not share a clean environmental window, so the pairing is already under pressure before behaviour is even considered.

Their flow expectations are close enough to combine: Willisii prefers gentle, low-flow water, while Green Spotted Puffer (Brackish) prefers moderate flow.

Water type is a serious mismatch: Willisii is listed for freshwater, while Green Spotted Puffer (Brackish) is listed for brackish water.

Fish Pressure and Plant Resilience

Green Spotted Puffer (Brackish) does not put unusual pressure on this plant compared with harder fish-plant combinations.

Willisii has moderate cover density, high uproot resistance, and standard leaves. It can also help with shrimp refuge, grazing surfaces, and breaking up sight lines.

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

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

Layout Fit

Willisii is a rosette / crown plant usually used foreground and midground.

Green Spotted Puffer (Brackish) is a puffer, so the pairing works best when the planting style supports how that fish uses space and cover.

Willisii reaches about 20 cm tall by 15 cm wide and is usually rooted in substrate with nutrient-rich substrate preferred. 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 shrimp refuge, grazing surfaces, and line-of-sight breaks. Place it where Green Spotted Puffer (Brackish) 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.
