Okay just did further research on the brittle star as well as further research on the sea apples.
The only brittle star I could find that is "rumoured" to have eaten fish is a green one, and this thing is definitely purple. Plus fish bodies were not eaten or ravaged, so if the brittle star was preying on the fish I think their little bodies should have shown more evidence of same. The only thing we noticed on the dead fish was that their gills were a bit puffy.
The sea apples are one of the first thing that I put into the aquarium and they can be seen feeding daily - that is, one feeder tentacle after another is placed in their mouths, they are breathing out of their butts fine (cool feature, eh?) and they do not appear stressed at all. Their positioning within the tank did not change at all on the night of death in question.
I am going to try that bottle thingy tonight. If I come up with anything weird, or anything changes, I shall of course update this thread.
Canabis, that is exactly what I am thinking.
