School of four line wrasses?

[TCU Reefer]

Is this possible to have several of these in one tank (215g)?

Will they be aggressive towards each other?

I'd like to get about four of these but need to know if it will be trouble.

 

[Amphiprion]

This species is a secretive loner--they don't school or shoal. They will act aggressively toward eachother, maybe even in a 215 gallon. I would stick with one or two at the very most (two individuals may be a problem).

Amphiprion is right, they do not school or shoal and in fact will attempt to kill each other (and probably succeed). They are also incompatible with fairy wrasses.

Sorry Amphiprion and Steve but you are wrong.

Pseidocheilinus hexataenia and tetratenia live in groups and can be kept in harem groups. See the picture in Rudie Kuiters book for hexataenia!

I kept a group of 1,3 of hexataenia which spawned every night. I gave them away to a breeder for working on them. And yes they are still quite agressive against other new fish.
A friend even keeps a group of hexataenia and tetrataenia peacefully in the same tank!

The sucess factor is to add small juvenile fish together in the tank and let them sort out who will be the domination male.

tetratania are generally quite mellow. I would also have to dissagree with them being fairy wrasse killers. hexatainia however is a fairy wrasse killer and not a very friendlt tankmate in general. I think 3-4 tetra's would be fine in a tank that big. I have kept 2 tetras and a flame wrasse together with no drama. GEtting the tetras as juvis would likley enhance the likleyhood of success. I would count on them schooling though.

That last sentance was supposed to say- I would NOT count on them schooling.
