Is Scarlet Temple a Good Plant for Blind Cave Tetra?

Scarlet Temple fits inside the water range normally used for Blind Cave Tetra. The shared window is about 20 to 25 °C, pH 6.5 to 7.5, and 8 to 12 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.

Blind Cave Tetra does not put unusual pressure on this plant compared with harder fish-plant combinations.

Scarlet Temple has moderate cover density, moderate uproot resistance, and standard leaves. It can also help with breaking up sight lines, fry refuge, and shrimp refuge.

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

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

Scarlet Temple is a stem plant usually used midground and background.

Blind Cave Tetra is a characin, so the pairing works best when the planting style supports how that fish uses space and cover.

Scarlet Temple reaches about 45 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, fry refuge, and shrimp refuge. Place it where Blind Cave Tetra can actually use that structure instead of hiding the plant where it cannot do much.

This is a sensible planted-tank choice for Blind Cave Tetra, 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 Blind Cave Tetra actually swims, shelters, or uses cover.
