Added the loaches and ottos into the tank this afternoon. The Khuliis immediately went into hiding, which was good to see, but as soon as I fed the puffers, they also came out to get a bite. Fortunately even when Achilles saw the loaches he kind of ignored them and swam away, hopefully this will be a good sign as to their future. I don't want to come home from dinner and see three dead loaches. The Ottos that I got are huge this time, and they look very healthy, which is great. I think I'm going to move Achilles into a private tank at my girlfriend's place as soon as I get the chance.
