This is from April 25 to May 3...
( which is Day 10 to Day 18 )

It's the exam period so we didn't take much of our observations because of the exchange of classes. Due to that, we also didn't get to be with the fishes and so we would just go to the system at least once a day when ever its possible. We would also use this precious time to feed our fishes and clean up our tank a little bit. On May 2, Friday, one of our Mouse Lily had died due to man kind. We suspect that is the Secondary Fours who have been contaminating our system by putting food and other unnecessary stuff while they were using our class for the whole of the exam period. This incident had also caused most of our fishes to die but luckily... they didnt ! Yeah ! :DDDD
