Shared Tank Conditions

Tiger Lotus fits inside the water range normally used for Molly (Sailfin/Black/Dalmatian). The shared window is about 24 to 28 °C, pH 7.5 to 8, and 12 to 15 dGH, which gives you enough room to aim for stable middle-ground conditions.

Their flow expectations are close enough to combine: Tiger Lotus prefers gentle, low-flow water, while Molly (Sailfin/Black/Dalmatian) prefers moderate flow.

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

Molly (Sailfin/Black/Dalmatian) does not put unusual pressure on this plant compared with harder fish-plant combinations.

Tiger Lotus has moderate cover density, high uproot resistance, and delicate leaves. It can also help with surface cover, breaking up sight lines, and spawning sites.

This plant adds the denser cover that Molly (Sailfin/Black/Dalmatian) usually appreciates.

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

Layout Fit

Tiger Lotus is a bulb / tuber plant usually used midground and background.

Molly (Sailfin/Black/Dalmatian) is a livebearer, so the pairing works best when the planting style supports how that fish uses space and cover.

Tiger Lotus reaches about 60 cm tall by 40 cm wide and is usually bulb / tuber on or partly 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 surface cover, line-of-sight breaks, and spawning sites. Place it where Molly (Sailfin/Black/Dalmatian) can actually use that structure instead of hiding the plant where it cannot do much.

Practical Recommendation

This is a sensible planted-tank choice for Molly (Sailfin/Black/Dalmatian), 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 Molly (Sailfin/Black/Dalmatian) actually swims, shelters, or uses cover.

Best Use Case

Tiger Lotus is a strong choice for Molly (Sailfin/Black/Dalmatian) when you want the plant to do real work in the tank, not just survive in the background. The pairing tends to perform best when the plant's cover, resilience, or placement naturally supports how the fish moves, hides, or claims space.
