Is River Buttercup a Good Plant for Green Spotted Puffer (Brackish)?

River Buttercup and Green Spotted Puffer (Brackish) 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: River Buttercup is listed for freshwater, while Green Spotted Puffer (Brackish) is listed for brackish water.

Green Spotted Puffer (Brackish) 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.

River Buttercup has moderate cover density, low uproot resistance, and standard leaves. It can also help with shrimp refuge, grazing surfaces, and fry refuge.

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

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

River Buttercup is a stolon / runner plant usually used foreground, carpeting, 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.

River Buttercup reaches about 15 cm tall by 20 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 fry refuge. Place it where Green Spotted Puffer (Brackish) can actually use that structure instead of hiding the plant where it cannot do much.

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.

River Buttercup is usually the wrong plant for Green Spotted Puffer (Brackish) 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.
