Is Floating Water Sprite a Good Plant for Electric Blue Crayfish?
Floating Water Sprite is not recommended for Electric Blue Crayfish. The issue is practical, not cosmetic: electric Blue Crayfish is likely to chew or tear this plant before it settles in.

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.
42/100
The fish is likely to outgrow, uproot, or out-pressure the plant.
Workable overlap
Shared range: 20-25°C, pH 6.5-8, 6-15 dGH.
High
Electric Blue Crayfish may chew, uproot, or stress this plant.
High cover
Floating Water Sprite helps with provides surface cover, good refuge for fry, good refuge for shrimp, useful spawning site, good grazing surface, and breaks lines of sight.
Plant and Fish Fit Notes
Use these signals to decide whether the plant is doing useful work for the fish, or whether it is only surviving beside it.
Overlap: 20-25°C.
Overlap: pH 6.5-8.
Overlap: 6-15 dGH.
Flow expectations are close enough for one layout.
Plant pressure: High.
Shared Tank Conditions
Floating Water Sprite fits inside the water range normally used for Electric Blue Crayfish. The shared window is about 20 to 25 °C, pH 6.5 to 8, and 6 to 15 dGH, which gives you enough room to aim for stable middle-ground conditions.
Their flow expectations are close enough to combine: Floating Water Sprite prefers gentle, low-flow water, while Electric Blue Crayfish prefers moderate flow.
Both are suited to freshwater, so salinity does not add an extra planning problem.
Fish Pressure and Plant Resilience
Electric Blue Crayfish puts heavy pressure on plants, so this species is likely to be chewed, uprooted, or stressed in day-to-day use.
Floating Water Sprite has high cover density, low uproot resistance, and delicate leaves. It can also help with surface cover, fry refuge, shrimp refuge, spawning sites, grazing surfaces, and breaking up sight lines.
The plant helps break up sight lines, which can soften territorial behaviour.
The limiting issue is electric Blue Crayfish is likely to chew or tear this plant before it settles in.
Layout Fit
Floating Water Sprite is a floating plant usually used floating.
Electric Blue Crayfish is an invertebrate, so the pairing works best when the planting style supports how that fish uses space and cover.
Floating Water Sprite reaches about 15 cm tall by 30 cm wide and is usually free-floating 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 surface cover, fry refuge, shrimp refuge, spawning sites, grazing surfaces, and line-of-sight breaks. Place it where Electric Blue Crayfish 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: Electric Blue Crayfish is likely to chew or tear this plant before it settles in.
Best Use Case
Floating Water Sprite is usually the wrong plant for Electric Blue Crayfish 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.
