The butterflyfish can be tricky to keep long term IMOOne of the best- Yellow coris wrasse
canary blenny
yellow watchman goby
lemon butterfly
yellow cubicus boxfish
and the box fish .. I was just researching them as I was going to get one .
Beautiful fish . Slower moving but the downfall maybe someone can correct me if I’m wrong .
they can nuke a tank in seconds with the toxic slime coat ..
is that only a few species of box fish or when threatened ?
