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

72/100

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

River Buttercup needs thoughtful placement and anchoring.

Layout value

Moderate cover

River Buttercup helps with good refuge for shrimp, good grazing surface, and good refuge for fry.

Shared Tank Conditions

River Buttercup and Silver Tiger Perch (American Tigerfish) 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 can work if the tank stays in the shared part of freshwater and freshwater to lightly brackish water conditions.

Fish Pressure and Plant Resilience

Silver Tiger Perch (American Tigerfish) 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 their hardness ranges are too far apart for a reliable long-term match.

Layout Fit

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

Silver Tiger Perch (American Tigerfish) is an oddball fish, 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 Silver Tiger Perch (American Tigerfish) 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: Their hardness ranges are too far apart for a reliable long-term match.

Best Use Case

River Buttercup is usually the wrong plant for Silver Tiger Perch (American Tigerfish) 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.
