veliferium

even with eggcrates it's not fully effective. they may jump through.

yes jumping is a problem especially with flashers.

may i ask what species?

i am not very sure yet.

will post a photo to let you guys id soon.

definitely not the reddish ones(lineopunctatus,cyaneus).

they all look orangy with blue stripes.and they're pretty small,like 2 inches from head to tail?

they caught my eye when they were flashing their little red single dorsal fins.

Paracheilinus flavianalis.

flavianalis have usually one (rarely 2-4) and it is red. a picture will confirm the ID.

can be differentiated with mccosker wrasse (also 1 filament). but flavianalis has yellow anal fin and red dorsal filament.
