Eric and Maggie added siding to the main tank:
Spencer was absent, so I worked on running Neopixels with the Arduino:
/* Neopixel Ring- Single Red LED spins around circle; can be powered by +5V pin.
//if lots of LEDs need to be turned on at the same time, you can use an L298N Motor driver as a 5V supply( connect GND to GND, Vin(+12) to +12V, 5V out to
Neopixels power lead[red]
To avoid damage to Neopixels add a 500 ohm resistor into data line and 1000 uF capacitor across 5V supply. See Adafruit Neopixel Uberguide Best Practices

#include <Adafruit_NeoPixel.h>

// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS

Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN,
NEO_GRB + NEO_KHZ800);
void setup() {
pixels.begin(); //
This initializes the NeoPixel library.
}
void loop() {
// For a set of
NeoPixels the first NeoPixel is 0, second is 1, all the way up to the count of
pixels minus one.
for (int i = 0; i
< NUMPIXELS; i++) {
// pixels.Color
takes RGB values, from 0,0,0 up to 255,255,255
pixels.setPixelColor(i, pixels.Color(50, 0, 0)); // Moderately bright
green color.
pixels.show(); // This
sends the updated pixel color to the hardware.
delay(10);
pixels.setPixelColor(i, pixels.Color(0, 0, 0)); // Moderately bright
green color.
delay(10);
}
