Awesome update - I’d missed the last update so it felt like a lot has been happening
Tank is looking grand
For the back wall, you might try giving it a scrape to remove existing algae - which is apparently not to the Otos’ refined tastes (or they’re saving for a rainy day) - new “growth” may be more tempting
Return the glowlights - they are too agressive for the CPDs and do stress them, also can be difficult to get enough food to the slower eating CPDs without overfeeding
I’d go on a snail hunt, imagine them all laying 20-40 eggs and you see the tank takeover coming they do compete with the Otos for available food
