At 7:04 a.m. on a Saturday morning, it is January dark. Coffee on, gratitude so-so. Flick on the fish tank light, bright light. It illuminates a veritable forest of plants with neon tetras darting about. This is why I have a tank. For these January mornings when the southerly sun lags in the sky and will most likely be hidden by high flat gray. The fish tank is a bright waterscape, alive and thriving.
