pck,
most invertebrates are less tolerant of ammonia, nitrites and nitrate spikes.
i would really recommend u to read up of types of fishes/invertebrates.. If anything goes wrong even in an established tank, the inverts would die first.
ive been where u were, excited and cant wait to cycle and 2 clowns had to die because of my ignorance.
btw im still a newbie, so my advice are cheap advice... hahaha
