My roommates and I have a fish.
To solve this, I used an ESP8266 to automatically turn on the lights in the morning and turn them off in the evening. Because the ESP doesn't have a built-in RTC, I sync every ten minutes with the NIST NTP servers (which likely makes this the most accurate timekeeping device in the house other than cell phones!) and fade the lights off at 7am and off at 9pm.
I began my prototyping with an ESP32 since I couldn't find my USB<->Serial adapter.
