Adult fishies seem to be doing fine; they are not thrilled by the temperature at present, but provided I shelter them from the worst of the heat, and feed them, they seem to be OK.
It’s possible there are cory babies in the aquarium; I will have to take a better look in daytime, however the female may have spawned - looking a lot slimmer than she was a day or two ago. If so, they are in for a dangerous time (parent fish will quite happily eat spawn or eggs, by and large).
A little difficult to tell yet, between random detritus being moved by water flow, and a living animal moving under power. Usually when/if they get it a bit bigger it will be obvious.
