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

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

Layout value

High cover

Sweet Potato helps with good refuge for fry, good refuge for shrimp, provides surface cover, breaks lines of sight, and useful spawning site.

Shared Tank Conditions

Sweet Potato and Ceylon 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: Sweet Potato prefers gentle, low-flow water, while Ceylon Puffer (Brackish) prefers moderate flow.

Water type is a serious mismatch: Sweet Potato is listed for freshwater, while Ceylon Puffer (Brackish) is listed for brackish water.

Fish Pressure and Plant Resilience

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

Sweet Potato has high cover density, high uproot resistance, and standard leaves. It can also help with fry refuge, shrimp refuge, surface cover, breaking up sight lines, and spawning sites.

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.

Layout Fit

Sweet Potato is a other usually used background and attached to hardscape.

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

Sweet Potato reaches about 60 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 fry refuge, shrimp refuge, surface cover, line-of-sight breaks, and spawning sites. Place it where Ceylon 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.

Best Use Case

Sweet Potato is usually the wrong plant for Ceylon 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.
