Pearlscale gone

I just posted on Sunday that my 2 pearlscale still alive . but never knew.. yesterday i found one of them floating lifeless in the fish tank..sob sob

Morning i still fed them like usual, cos everytime i open my balcony sliding door, the two pearlscale will swim excitedly asking for food.. so i cant bear seeing them like that, usually will feed them one or two fish feed.. cannot feed too much else will dirty the water too soon and will cause them to die faster.

When i fed them, only one (the bigger one) swim excitedly on top of the water to eat the other one remain below.. i tot maybe he is eating those food dropping below..

never knew, evebing when i came home, he died le.. so sad.. now left with one.

dunno whether should get one more or not...
