Quick update. Albus seems to be perking up. He's swimming around his tank. Mainly around his heater which incidentally does not seem to be working. Gah. Ordered a new one that should arrive in a couple days.
I can watch him now but the second a reach my hand over, either to grab something on the other side of the tank or to try and feed him he hides. I tried to feed him a couple pellets. He ate the first one and then nothing. Come on buddy, I got you the good stuff.
His fins appear a bit more open too. I'd take some pictures but the water is kind of a nasty yellow (IAL)
