Care guide at a glance
Iriatherina werneri
Description
An extraordinary small rainbowfish, the males carrying trailing black filaments from the dorsal and anal fins that they flick constantly in display. Delicate-looking and genuinely unusual.
Feeding
Very small foods only. The mouth is tiny. Powdered flake, crushed micro-pellets, frozen cyclops and baby brine shrimp.
Compatibility
Entirely peaceful and easily outcompeted. Best with other small, slow feeders. Avoid fast fish that clear food before the threadfins reach it, and avoid any fin-nippers.
Behaviour and personality
Males display to each other constantly, spreading their fins and flicking the long filaments. Best kept with several males present so the display happens.
Before you buy
The two common failures are starvation, because faster tankmates take the food, and damaged filaments from nipping. Choose tankmates with both in mind.
