Since we are talking about Juvenile clown triggers ........ As juveniles they can be great fish, if fed a variety of foods they can even live in reef tanks without touching a thing, small clown triggers live around reefs in the wild.
You see, as this fish matures it will become territorial, the larger the fish the larger the territory. Only time will tell how large of a territory your trigger will require, they can spend much of their day patrolling their territory........ So as juveniles they are great, keeping these triggers in a small glass box as they mature, is another issue.
If you don't mind me asking:
Do you just plan on keeping a juvenile and getting rid of this fish as it matures?
I have seen a few mature clown triggers that were well behaved in tanks over the years and never touched a thing, but the majority ruled and would kill tank mates as they matured because of space and territorial needs.
If you do go this route, Keep this trigger well fed, offer the space that it needs and see where it takes you. Believe me this is one trigger I would love to have and no matter how much I read about it over the years, I am still not brave enough to risk it.
