Reviewed by Guidarium Editorial DeskUpdated May 2, 2026
Not Recommended

Giant Baby Tears is not recommended for African Arowana. The issue is practical, not cosmetic: african Arowana is likely to uproot this plant while digging through the substrate.

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

68/100

The fish is likely to outgrow, uproot, or out-pressure the plant.

Water match

Workable overlap

Shared range: 24-28°C, pH 6.5-7.5, 5-15 dGH.

Plant pressure

High

African Arowana may chew, uproot, or stress this plant.

Layout value

High cover

Giant Baby Tears helps with breaks lines of sight, good refuge for shrimp, and good refuge for fry.

Shared Tank Conditions

Giant Baby Tears fits inside the water range normally used for African Arowana. The shared window is about 24 to 28 °C, pH 6.5 to 7.5, and 5 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.

Both are suited to freshwater, so salinity does not add an extra planning problem.

Fish Pressure and Plant Resilience

African Arowana puts heavy pressure on plants, so this species is likely to be chewed, uprooted, or stressed in day-to-day use.

Giant Baby Tears has high cover density, low uproot resistance, and delicate leaves. It can also help with breaking up sight lines, shrimp refuge, and fry refuge.

It gives African Arowana useful visual shelter and line-of-sight breaks.

The limiting issue is african Arowana is likely to uproot this plant while digging through the substrate.

Layout Fit

Giant Baby Tears is a stem plant usually used midground and background.

African Arowana is an oddball fish, so the pairing works best when the planting style supports how that fish uses space and cover.

Giant Baby Tears reaches about 25 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 line-of-sight breaks, shrimp refuge, and fry refuge. Place it where African Arowana 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: African Arowana is likely to uproot this plant while digging through the substrate.

Best Use Case

Giant Baby Tears is usually the wrong plant for African Arowana 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.
