We haven’t been seeing Otto much for nearly a week now, and we suspected that he was most likely hiding somewhere in the tank and only appearing when the lights were off. However, several days ago when Otto finally did appear, Ling observed that he look tremendously pale and had lost much of his body colouration. Yesterday he wasn’t swimming around very much any more, spending most of his time lying very weakly on the gravel. He finally expired today at around 4:30 p.m.
We’re not sure what happened since the other critters seem to be doing OK, although Tinny and Patches seem to be losing a few of their scales (they haven’t lost their appetites yet). It’s possible that his source of food – algae – has diminished though, and while I did try feeding him small bits of Hikari algae wafers, he didn’t seem to take to them.
Rest in peace, Otto.
