The water has been cleaing up for Gillbert. No idea what was going on with my sprouts causing so much water pollution but it's been nice to see Gillbert's water actually improve for once. I probably need to clean the outside of his tank more than the inside right now. His tank is positioned beside my kitchen sink and he gets hit by a small amount of spray. Was hard to see just how dirty the outside was while the inside was so filthy.
Gillbert seems a bit more lively after the water change and it's good to see him chasing after his food more aggressively and being more responsive when I interact with his tank.
Gillbert is the best fish ever!
