Multiple choice & Silly tank

OK, slept at 11 and woke at 3am. Got up as my lights were still on (fell asleep while reading the past year questions in bed) and Mr. Ye's sms'es on my horridly loud phone woke me up. Also because of a stupid stummyache, which turned out to be diarrhoea.

So for now, it's back to the MCQs till I get tired enough to sleep again. Doubt so though, it rarely happens when I've woken up.

Freaking tankmates are irritating me. Went to check on the tank for 2 mins just now (Was making coffee, yum!) and saw that anemone was hiding under rocks AGAIN. And just yesterday afternoon I discovered that the dreaded zoanthid-eating nudibranchs are back AGAIN! I waged a full war on these pests a couple of months back, and they finally receeded. Involved manually picking them out and dipping the affected zoanthids in hyposaline water. Just saw one of my zoanthid colonies being heavily infested, so I took that one out. Thinking of throwing the whole damn thing away. But it's a sin to kill corals. =(

Enough blabbering. Back to the darling questions!!
