Is Micro Sword a Good Plant for Figure 8 Puffer (Brackish)?

Micro Sword fits inside the water range normally used for Figure 8 Puffer (Brackish). The shared window is about 24 to 28 °C, pH 7.5 to 7.5, 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.

Water type can work if the tank stays in the shared part of freshwater to lightly brackish water and brackish water conditions.

Figure 8 Puffer (Brackish) does not put unusual pressure on this plant compared with harder fish-plant combinations.

Micro Sword has high cover density, high uproot resistance, and tough / leathery leaves. It can also help with shrimp refuge, fry refuge, grazing surfaces, and spawning sites.

Its structure adds useful refuge value beyond the normal visual role of the plant.

There is no special plant-pressure warning here, so solid anchoring and stable husbandry matter more than unusual protection.

Micro Sword is a stolon / runner plant usually used foreground and carpeting.

Figure 8 Puffer (Brackish) is a puffer, so the pairing works best when the planting style supports how that fish uses space and cover.

Micro Sword reaches about 7 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, fry refuge, grazing surfaces, and spawning sites. Place it where Figure 8 Puffer (Brackish) can actually use that structure instead of hiding the plant where it cannot do much.

This is a sensible planted-tank choice for Figure 8 Puffer (Brackish), especially when you want the plant to do real work as cover, sight-line structure, or habitat detail.

The decision should center on layout quality: keep the plant in the zone where Figure 8 Puffer (Brackish) actually swims, shelters, or uses cover.
